Definitions

  • the invention relates to a hand lever operated pump for Output of liquid or pasty media, with a pumping chamber that has an inlet valve and an outlet valve has, further with a pump piston, which with a Pump cylinder interacts, and with a cover plate for a removal opening of a storage vessel, the top of is penetrated by a suction pipe, and with a return spring.
  • Such a pump is, for example, from the PCT application WO 92/04128 known.
  • PCT application WO 92/04128 known.
  • the invention proposes that the return spring on the storage side is supported on the cover plate.
  • the return spring is in the reservoir involved.
  • the structure of the pump above the cover plate can thereby be reduced or the Space above the cover for a comparative large pump cylinder or pump piston also used become. The latter is important, for example, if relatively large output quantities are to be achieved.
  • the arrangement described is also assembly advantageous.
  • the spring can be against the bottom Soil are used. Must be above the cover no spring between the moving parts of the pump to be assembled. The one mentioned is particularly advantageous Embodiment if at the same time with the movement of the pump piston or the pump cylinder and The suction pipe is lowered.
  • the return spring can continue on the intake manifold or an intake manifold bracket be supported. With a pumping movement the return spring is thus compressed against the cover base.
  • the bellows is in the plastic injection molding process manufactured. Further it is preferred if the bellows in this regard its wall is closed, but it is further preferred that in the interaction between the cover plate and the return spring or the Bellow and / or in the interaction between the Intake manifold or the intake manifold bracket and the bellows the latter a passage opening for ventilation of the pantry.

It is also provided that the insert part forms a tubular guide part for the suction pipe or the suction pipe holder. It is advantageous if an air passage opening between the guide part and the suction pipe holder is trained.
  • the insert is preferably also procured from a soft PVC or similar material, which also acts as a seal when screwing on or Snap connection of the snap cap or screw cap with a Neck of a storage container. An end face of the Halses then lies against the soft PVC.
  • the pump piston with a bent course is formed and the pump cylinder in a neck area of the pump in an in arranged substantially vertically movable is.
  • the pump piston is therefore extended through a corner guide of the pump piston. This makes it possible to in the pump cylinder Arrange the neck area of the pump and essentially to move vertically relative to the fixed piston.
