Definitions

  • the invention relates to a fuel tank for a motor vehicle with a refueling vent and a operational venting having venting device with a venting line of the refueling vent and with one to in designated areas of the fuel tank ge ⁇ led vent line of the operational venting, wherein the refueling vent and the operating ventilation via a line with a Activated carbon filter are connected.
  • Such fuel tanks are commonly used in today's motor vehicles and are known in practice.
  • Be ⁇ operating venting allows escape of fuel vapors during operation of the motor vehicle and a subsequent flow of air at a consumption of the fuel.
  • the refueling vent ⁇ derives from the charged fuel displaced air from the fuel tank through the charcoal filter.
  • the charcoal filter communicates with the environment to allow pressure equalization.
  • the operating ventilation and refueling are laboriously mounted on the fuel tank.
  • the invention is based on the problem of designing a Kraftstoffbe ⁇ container with a venting device so that the fuel tank with the venting device is particularly easy to assemble and manufacture.
  • the refueling vent and the operating vent have a common container and that the container each has a chamber for the refueling vent and the strigentlüf ⁇ tion.
  • the essential components of the operating ventilation and the refueling vent can be preassembled into a structural unit and used in the fuel tank according to the invention.
  • the common, the chambered container can also particularly easy fer ⁇ term.
  • the separation of the container in the two chambers allows reliable management of the fuel vapors through the activated carbon filter.
  • the chambers are preferably completely separated from each other.
  • the construction work for the venting device can be kept particularly low when the refueling vent and the operating vent each have a valve and when the valves are connected to the leading to the activated carbon filter line.
  • the valves thereby prevent liquid fuel from reaching the activated carbon filter and damaging it.
  • control of the refueling ventilation designed according to another advantageous embodiment of the invention structurally particularly simple if at least one of the valves is designed as a float valve.
  • An emptying of the chambers of the ventilation device ges ⁇ taltet particularly simple if the refueling vent and the operational venting each have an ejector on ⁇ and when suction of suction jet pumps are connected to a respective chamber of the refueling vent and the operation ⁇ vent.
  • the suction ⁇ jet pumps from a within the fuel tank on ordered fuel pump supplied with fuel as a propellant.
  • the chambers of the breather ⁇ processing device during operation of the motor vehicle are always empty. Therefore, designed as a float valves valves to close the lines to the activated carbon filter even in a rollover of the motor vehicle.
  • the valves of the venting device therefore also serve as so-called roll-over valves.
  • An escape of fuel vapors from the fuel tank can be kept particularly low when the container is disposed within the fuel tank.
  • the number of sealing points of the fuel tank is kept particularly low.
  • a particularly accurate limitation of feedable the fuel tank amount of fuel is ensured when the vent line of the refueling vent is performed up to a designated cut-off point of the fuel tank and when the tank is below the cut-off is angeord ⁇ net.
  • the vent of the fuel tank is closed when the shutdown point. Then no more air can escape from the fuel tank and thus no fuel can be refilled.
  • the shut-off point is set thanks to the invention of the free end of the vent line of the refueling vent.
  • FIG. 1 shows a fuel tank according to the invention with a venting device in a Thomasdar- position
  • 2 is a schematic sectional view through a container of the venting device of FIG. 1.
  • a vent means 4 comprising a container 5 and a plurality of vent lines 6, 7, 7 ' , One of the vent lines 6 leads to the filler neck 2 of the fuel tank 1 up to a shut-off point.
  • the vent 4 is connected via a line 8 with an activated carbon filter 9.
  • the activated carbon filter 9 is shown here outside of the fuel tank 1 and is connected to the environment.
  • the activated carbon filter 9 can also form with the container 5 of the venting device 4, not shown, arranged within the fuel tank 1 structural unit.
  • a flange 10 arranged above the venting device 4 closes a mounting opening 11 in the flange
  • Fuel tank 1 The fuel delivery unit 3 sucks fuel from the fuel tank 1 and promotes this via a flow line 12 to an internal combustion engine, not shown, of the motor vehicle. Furthermore, the fuel delivery unit 3 conveys fuel via a branch 13 to the ventilation device 4.
  • FIG 2 shows a sectional view through the container 5 of the venting device 4 of Figure 1.
  • the container 5 has two chambers 14, 15. One of the chambers 14 is provided for a refueling vent 16, while the other of the chambers 15 is provided for an operating vent 17 of the fuel tank 1 of Figure 1.
  • the Betankungsentlüf ⁇ tung 16 has led to the cut-off vent line 6.
  • the operation of vent 17 has the run in the corner regions of the fuel tank 1 Entlwillungslei ⁇ obligations 7, 7 '.
  • the chambers 14, 15 are each one with connected to the activated carbon filter 9 guided line 8. Before the guided to the activated carbon filter 9 lines 8 each have a valve 18, 19 are arranged.
  • the valve 19 of the Medent ⁇ ventilation 17 is formed as a pressure-holding valve and enables the outlet of fuel vapors only above a designated pressure.
  • Suction ports 20, 21 of the suction jet pumps 22, 23 are in lower portions of the chambers 14, 15.
  • the suction jet pumps 22, 23 are each supplied via propellant lines 24, 25 with fuel, fortune fuel from the chambers 14, 15 to suck and return via collecting ⁇ lines 26, 27 in the fuel tank. 1
