An electric pump that pumps up the fuel in the fuel tank and sends it to the fuel take-off pipe; and a regulator valve that adjusts the discharge pressure by returning a part of the fuel discharged from the electric pump to the fuel tank. , A force bra for holding the outer terminal is integrally projected on the upper surface of the mounting base member, and an inner terminal protruding from the lower surface of the mounting base member is connected to the outer terminal, and is projected on the upper surface of the electric pump. In the fuel supply module, which is connected to each other via a lead wire, the fuel discharge pipe of the electric pump is fitted to the mounting base member with a downward force. The fuel discharge pipe is integrally formed with a connecting cylinder that communicates with the fuel take-out pipe, while the inner terminal is disposed radially outward of the electric pump, and the legule is connected between the inner terminal and the connecting cylinder. The first feature is that the control valve is attached to the attachment base member, and a pressure adjusting passage for connecting the valve hole of the regulator valve and the fuel take-out pipe is formed in the attachment base member.

[0006] In addition to the first feature, the present invention provides the fuel discharge pipe and the power supply terminal protruding from the upper end surface of the electric pump on both sides of the axis of the electric pump. The second feature is that the regulator valve is disposed immediately above the power supply terminal.

[0007] Further, in addition to the second feature, the present invention has a third feature that the regulator valve is arranged such that at least a part thereof is located above the upper surface of the mounting base member.

Furthermore, in addition to any one of the first to third aspects of the present invention, the fuel take-out pipe and the force bra are mounted on the plane of the mounting base member with their openings directed outwardly opposite each other.

Example 1

[0017] First, in FIGS. 1 to 3, the ceiling of a fuel tank 搭載 mounted on a vehicle such as a motorcycle. On the wall 1, the fuel supply module M of the present invention for supplying the fuel in the fuel tank T to the fuel injection valve I of the engine is attached.

[0018] The fuel supply module M is formed integrally with the mounting base member 2, the electric pump Ep disposed directly below the mounting base member 2, and the axial direction thereof vertically, and the mounting base member 2. The upper pump holder 3A is detachably coupled to the upper pump holder 3A, and the lower pump holder 3B that accommodates and holds the electric pump Ep in cooperation with the mounting base member 2 and the lower end of the electric pump Ep. And an attached fuel strainer 4.

In the ceiling wall 1 of the fuel tank T, an opening 5 for inserting the electric pump Ep is provided, and an attachment ring 6 surrounding the opening 5 is fixed. This mounting ring 6 is fixed with a plurality of mounting bolts 7, 7.

[0020] The mounting base member 2 has a disk-like flange portion 2a that is superimposed on the upper surface of the mounting ring 6 so as to close the opening 5. The flange portion 2a is provided with a plurality of bolt holes 11, 11 "arranged along the outer periphery thereof, and a plurality of mounting bolts 7, 11,. The mounting base member 2 is fixed to the mounting ring 6 by means of a plurality of nuts 8, 8... Screwed to them, and the flange 2 a and the ceiling wall 1 of the fuel tank T are connected to each other. An annular sealing member 9 that seals the opening 5 is interposed between them.

[0021] The mounting base member 2 is made of a synthetic resin, and a fuel take-out pipe 12 protruding in the horizontal direction outside the fuel tank T is formed on the upper portion of the flange portion 2a. The outer end of 12 is connected to a fuel supply pipe 33 connected to the fuel injection valve I of the engine.

[0022] An upper pump holder 3A is formed on the lower surface of the flange portion 2a. The upper pump holder 3A has a cylindrical shape that protrudes into the fuel tank T and fits into the outer peripheral surface of the upper half of the electric pump Ep. The upper pump holder 3A has a letter-like shape with the lower end open. A plurality of locking grooves 13F are provided at equal intervals in the circumferential direction.

[0023] On the other hand, the lower pump holder 3B is adapted to accommodate and hold the lower half of the electric pump Ep. It is formed into a cylindrical shape by synthetic resin. At that time, multiple T-shaped locking claws 13M projecting from the upper end force are formed in one piece. The lower pump holder 3B is coupled to the upper pump holder 3A by engaging these locking claws 13M with the locking grooves 13F. Thus, the electric pump Ep is accommodated and held between the upper pump holder 3A and the lower pump holder 3B.

As clearly shown in FIG. 2, the electric pump Ep is composed of an electric motor E with the rotor 20 directed in the vertical direction and a fuel pump P driven by the electric motor E. The electric motor E is coupled to a cylindrical stator 17 having a plurality of magnets 17a arranged in the circumferential direction on the inner peripheral surface, an upper bearing bracket 18 that is caulked to the upper end of the stator 17, and a lower end portion thereof. A lower bearing bracket 19 and a rotor 20 on which the rotor shaft 20a is supported by the upper and lower bearing brackets 18, 19.

[0025] The fuel pump P is rotatably accommodated in the pump chamber 22 and a pump case 23 that is caulked to the stator 17 together with the lower bearing bracket 19 so as to define a pump chamber 22 between the lower surface of the lower bearing bracket 19 The pump impeller 24 connected to the lower end portion of the rotor shaft 20a is configured as a Wesco type.

The pump case 23 is provided with a suction port 25 that opens into the pump chamber 22, and the fuel strainer 4 disposed at the bottom of the fuel tank T is connected to the suction port 25, and this fuel strainer 4 is attached to a support shaft 26 projecting from the lower surface of the pump case 23. The lower bearing bracket 19 is provided with a discharge port 27 that communicates with the pump chamber 22 and the stator 17.

[0027] The upper bearing bracket 18 is formed with a fuel discharge pipe 30 protruding upward and having a final discharge port 34 communicating with the inside of the stator 17, and inside the final discharge port 34. A check valve 31 is provided to prevent the backflow of fuel to the engine. The fuel discharge pipe 30 is fitted to the inner peripheral surface of the connecting cylinder 29 protruding integrally with the lower surface of the mounting base member 2 through a seal member 32 with a downward force.

[0028] The mounting base member 2 includes a series of L-shaped fuel passages 28 that run inside the fuel take-out pipe 12 and the connecting cylinder 29 and communicate with the inside of the fuel discharge pipe 30, and the bending of the fuel passage 28. A pressure regulating path 35 is formed which branches from the section and opens the downstream end into the fuel tank T. The pressure regulating path 35 is a pressure regulating path formed on the extension line of the fuel passage 28 on the fuel take-out pipe 12 side. The upstream portion 35a of the passage and the downstream end portion 35b of the pressure adjusting passage upstream portion 35a are bent downward and the downstream end is opened into the fuel tank T. The downstream portion 35b of the pressure adjusting passage 35b In addition, a regulator valve R for adjusting the pressure in the fuel passage 28 to a predetermined pressure suitable for fuel injection from the fuel injection valve I is provided.

The regulator valve R includes a bottomed cylindrical valve housing 36 formed separately from the mounting base member 2, and a valve hole 37 penetrating through the end wall of the valve housing 36. Thus, a conical valve seat 38 connected to the inner end of the valve hole 37 is formed. In the valve chamber 42 in the valve housing 36, a ball-shaped valve body 39 that can be seated on the valve seat 38, and a pressure regulating spring that urges the valve body 39 in a seating direction with the valve seat 38 with a predetermined set load. 40 and an annular retainer 41 that supports the fixed end of the pressure adjusting screw 40 are accommodated. The retainer 41 is press-fitted and fixed to the inner peripheral surface of the valve chamber 42, and is fitted into the opening of the valve chamber 42. It is retained by the retaining ring 46 that is locked.

[0030] The valve housing 36 is fitted and fixed to the holding hole 43 provided in the mounting base member 2 so as to open on the lower surface thereof, with the valve hole 37 facing upward. It communicates with the pressure regulating path upstream portion 35a through a through hole 44 provided in the ceiling wall. Thus, the through hole 44, the valve hole 37, and the valve chamber 42 constitute the pressure regulating path downstream portion 35b.

[0031] Furthermore, the attachment base member 2 is formed with a bag-like recess 45 branched from the pressure regulating path 35 upstream of the regulator valve R. In the illustrated example, the bag-like recess 45 is disposed on the extension line on the downstream end side of the upstream side 35a of the pressure regulating path, and therefore, when the mounting base member 2 is molded, the fuel passage 28, pressure regulating in the fuel take-out pipe 12 is formed. The upstream portion 35a and the bag-like recess 45 can be formed by a single core.

[0032] The fuel discharge pipe 30 is disposed on one side of the upper end surface of the upper bearing bracket 18, and a power supply terminal 47 of the electric motor E projects from the other side.

On the other hand, a force bra 48 for holding the outer terminal 49 is formed on the upper surface of the mounting base member 2, and the inner terminal 52 connected to the outer terminal 49 protrudes from the lower surface of the mounting base member 2. At the same time, a cylindrical guide cylinder 53 surrounding the inner terminal 52 is projected from the body. Connectors 50a and 50b attached to both ends of the lead wire 50 are connected to the power supply terminal 47 and the inner terminal 52, respectively, so that the inner terminal 52 and the power supply terminal 47 are connected. Are electrically connected to each other.

In the above configuration, the fuel discharge pipe 30 and the power supply terminal 47 on the upper surface of the electric pump Ep are arranged on both sides of the axis Y of the electric pump Ep.

[0035] The inner terminal 52 on the lower surface of the mounting base member 2 is disposed radially outward of the electric pump Ep, and the power supply terminal 47 between the inner terminal 52 and the connecting cylinder 29 on the lower surface of the mounting base member 2 is provided. A regulator valve R is arranged immediately above.

Furthermore, the regulator valve R is arranged so that at least a part thereof is located above the upper surface of the mounting base member 2.

[0037] Furthermore, the fuel take-out pipe 12 and the force bra 48 are arranged on the same diameter line X in the plan view of the mounting base member 2 with their openings directed outwardly opposite to each other. . Also, a holding hole 43 formed on the lower surface of the mounting base member 2 for fitting and holding the regulator valve R, a guide tube 53 formed on the lower surface of the mounting base member 2 and surrounding the inner terminal 52, and the connecting tube. 29 are arranged so that their axes are parallel to each other.

[0038] The regulator valve R disposed immediately above the power supply terminal 47 directs the open end of the valve chamber 42 toward the power supply terminal 47, so that the fuel discharged from the valve chamber 42 is moved to the electric pump around the power supply terminal 47. It falls on the top surface of Ep. In order to recirculate the dropped fuel into the fuel tank T, a notch window 51 is provided on the peripheral wall of the upper pump holder 3A.

Next, the operation of this embodiment will be described.

[0040] When the electric motor E is operated in the electric pump Ep, the pump impeller 24 is rotationally driven by the rotor shaft 20a. Accordingly, the fuel in the fuel tank T is sucked into the pump chamber 22 from the suction port 25 while being filtered by the fuel strainer 4, pressurized by the pump impeller 24, and pumped into the stator 17 from the discharge port 27. The fuel is supplied from the discharge port 34 to the fuel injection valve I through the fuel discharge pipe 30 and the fuel take-out pipe 12, that is, the fuel passage 28.

[0041] In the meantime, the pressure in the fuel passage 28, that is, the discharge pressure of the electric pump Ep, acts on the valve body 39 of the regulator valve R via the upstream side 35a of the pressure adjusting path, so that the discharge pressure of the electric pump Ep exceeds a predetermined value. Then, the valve body 39 opens against the set load of the pressure regulating spring 40, and the fuel passage 28 When a part of the fuel is discharged to the valve chamber 42 side and the pressure in the fuel passage 28 returns to a predetermined value, the valve element 39 is closed again by the set load of the pressure regulating spring 40. Thus, the pressure in the fuel passage 28 is automatically adjusted to a predetermined value, so that the fuel injection pressure from the fuel injection valve I is properly controlled.

[0042] The fuel discharged from the valve chamber 42 of the regulator valve R falls to the upper surface 18a of the upper bearing bracket 18 around the power supply terminal 47, that is, the upper surface of the electric pump Ep, and the notch of the upper pump holder 3A Passes through window 51 and returns to fuel tank T. Accordingly, since the periphery of the power supply terminal 47 is washed all the time with the discharged fuel of the regulator valve R force, the fuel does not stay around the power supply terminal 47, and the power supply terminal 4 due to moisture contained in the retained fuel 4 7 corrosion can be prevented in advance.

[0043] Further, the fuel that has dropped onto the upper surface 18a of the upper bearing bracket 18 is kinetic energy attenuated there, and then gently flows down from the cutout window 51 of the upper pump holder 3A onto the stored fuel in the fuel tank T. As a result, the falling sound of the fuel can be prevented.

[0044] If the discharge pressure pulsates during discharge of fuel from the electric pump Ep to the fuel passage 28, the pulsation is transmitted to the upstream side 35a of the pressure regulating path, but reaches the regulator valve R. Previously, the front force of the regulator valve R is also transmitted to the branched bag-like recess 45 and is attenuated by colliding with its inner wall. As a result, vibration of the valve body 39 of the regulator valve R due to the pulsation of the discharge pressure of the electric pump Ep can be prevented, so that an appropriate pressure regulating function of the regulator valve R can be secured and the fuel injection valve I It is possible to stabilize the fuel injection pressure.

[0045] Pressure pulsation may occur in the fuel passage 28 even when the fuel injection valve I is opened and closed. The pulsation can also be attenuated by the same action as described above, and the fuel passage 28 can be damped by opening and closing the regulator valve R. Pressure pulsation may occur in Fig. 28, which can also be attenuated by the same action as above.

[0046] The damping force and the pulsation damping of the pressure in the fuel passage 28 are achieved by an extremely simple damping means in which the front force of the regulator valve R branches the bag-like recess 45, so there is no increase in the number of parts and fuel supply. There is no need to increase the cost of module M.

[0047] By the way, the inner terminal 52 of the mounting base member 2 is located radially outside the electric pump Ep. After connecting the connector 50a at one end of the lead wire 50 to the power supply terminal 47 on the top surface of the electric pump Ep, The connector 50b at the other end of the lead wire 50 can be connected to the inner terminal 52 without being obstructed by the pump Ep. Therefore, there is no need to provide a work space for connecting lead wires in the vertical direction between the inner terminal 52 and the power feeding terminal 47. In the mounting base member 2, the force that creates a large space between the inner terminal 52 arranged radially outward of the electric pump Ep and the connecting cylinder 29 connected to the fuel discharge pipe 30 of the electric pump Ep. Since a large space is used for the installation of the regulator valve R, space efficiency is improved, and this regulator valve R also does not disturb the proximity of the electric pump Ep to the mounting base member 2. As a result, the mounting base member 2 and the electric pump Ep can be arranged close to each other, and the fuel supply module can be made compact.

[0048] Further, the fuel discharge pipe 30 and the power supply terminal 47 of the electric pump Ep are arranged on both sides of the axis Y of the electric pump Ep, and the regulator valve R is arranged directly above the power supply terminal 47. Therefore, the fuel discharge pipe 30, power supply terminal 47, and regulator valve R can be rationally concentrated above the electric pump Ep, and the fuel supply module M can be effectively connected. Can do. The fuel discharged from both the clamping force and the regulator valve falls around the power supply terminal, so the area around the power supply terminal is washed all the time by the discharged fuel from the regulator valve force, and the fuel stays around the power supply terminal. Therefore, corrosion of the power supply terminal due to moisture contained in the staying fuel can be prevented.

[0049] Further, the regulator valve R is arranged so that at least a part thereof is located above the upper surface of the mounting base member 2, so that interference with the regulator valve R can be avoided more reliably, and the mounting base can be prevented. This enables an effective close arrangement between the member 2 and the electric pump Ep, and the fuel supply module M can be further compacted.

Next, a method for forming the synthetic resin mounting base member 2 will be described with reference to FIGS. 4 and 5. FIG.

[0051] In forming the mounting base member 2 made of synthetic resin, a pair of left and right upper molds 60, 60 and one lower mold 61 are prepared. Between the left and right upper molds 60, 60 is an upper cavity 62a that forms a protruding portion of the upper surface of the flange 2a, that is, a fuel take-out pipe 12, a force bra 48, etc. The upper and lower molds 60, 60 are set so that the open / close surface P of both upper molds 60, 60 passes through both axes of the fuel take-out pipe 12 and the coupler 48. Between the upper molds 60, 60, the cores 64, 65 for forming the horizontal portions of the fuel passage 28 and the pressure adjusting passage 35 and the hollow portion of the force bra 48 are detachable.

[0052] Further, between the upper molds 60, 60 and the lower mold 61, there is formed a flange part 2a and a lower part thereof, that is, a lower cavity 62b for molding the flange part 2a, the connecting cylinder 29, the guide cylinder 53 and the like. ing

Thus, when forming the mounting base member 2, first, the inner terminal 52 is supported at a predetermined position of the lower mold 61, and then the left and right upper molds 60, 60 are closed to the lower mold 61. Then, the cores 64 and 65 are set, and the outer terminal 49 is supported by one of the cores 65. Next, the injection base member 2 can be formed by injecting and filling molten synthetic resin from the gate 63 into the cavities 62a and 62b. After the mounting base member 2 is solidified, the cores 64, 65 are pulled out, the left and right upper molds 60, 60 are opened to each other, and the upper mold 60, 60 and the lower mold 61 are opened. Member 2 can be removed

[0054] As described above, the mounting base member 2 can be molded with the left and right upper molds 60, 60, one lower mold 61, and a very small number of molds. The mounting base member 2 is arranged on the same diameter line X in a plan view so that the openings face oppositely opposite to each other, and a holding hole formed on the lower surface of the mounting base member 2 43 Therefore, the guide cylinder 53 and the connecting cylinder 29 with the fuel discharge pipe 30 are arranged so that their axes are parallel to each other.

The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention.
