  • the user activates the switch 5, 5' into the on position respectively by exerting finger pressure straight on the switch or by moving the dispensing head 16 from its rest position to its actuation position.
  • This activation of the switch brings about actuation of the drive means 3. More precisely, the motor 30 is actuated, thus driving the drive shaft 31 rotationally. In its turn, this shaft drives the drive wheel 32. This wheel then drives the connecting rod 33 which is moved with a reciprocating motion. This motion is then transmitted to the deformable membrane 24 which starts to oscillate. This movement of the membrane 24 can take place parallel to the main elongation axis X of the container and in particular can be coincident with this axis.
  • This oscillation takes place between a high point and a low point.
  • the movement of the membrane 24 from the high point to the low point closes the output valve. This movement creates a low pressure inside the pump chamber 20.
  • This low pressure then brings about the movement of the mobile member of the input valve 210 relative to its seat.
  • the input aperture 130 of the container can then communicate with the product inlet channel 23 of the pump chamber and product can thus be drawn from the container 1 towards the pump chamber 20.
  • the movement of the membrane from its low point to its high point closes the input valve.
  • This movement then creates a high pressure in the chamber and pushes the incompressible fluid into the product outlet channel 25.
  • the mobile member 220 of the output valve then comes unstuck from its seat, thus making this outlet channel 25 communicate with the output aperture 131 of the container.
  • the product can thus flow between the pump chamber 20 and the dispensing tube 14 of the container.
