Definitions

  • the present invention relates to a manual pump for dispensing a fluid product, this pump being intended to be associated with a fluid reservoir to thereby form a fluid dispenser.

This is a quite conventional and conventional design for a pump in the field of perfumery, cosmetics or pharmacy.
  • the volume of the pump chamber is determined and frozen for a particular pump model. In other words, it is generally not possible to change the volume of the pump chamber. It is however possible to adjust the volume of the pump chamber by acting on the top dead center corresponding to the rest position of the actuating rod and piston, as proposed for example in the document FR2719084 . It is intended in this document to drive more or less the collar in the pump body to adjust the volume of the pump chamber. One then acts on the stroke height of the piston. Therefore, the pusher mounted on the pump is movable to a reduced height, which may hinder the user who feels unable to push the button fully.
  • the present invention aims to overcome the aforementioned drawbacks of the prior art by defining a manual pump of standard capacity but which is capable of delivering a dose of fluid that is less than the volume of the pump chamber, without reducing the stroke piston and actuator rod and without reducing the volume of the pump chamber.
  • an object of the present invention is to dispense a partial dose of fluid product with respect to the capacity of the pump chamber.

  • the leak can be achieved at the inlet valve, and directly at the wall of the pump chamber which communicates directly with the fluid reservoir, and again so as to shunt the inlet valve by connecting the chamber pump directly to the dip tube.
  • additional return passages can be implemented independently of the return passages at the inlet valve in certain embodiments. Separate protection could be sought for these additional return passages.
