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 the 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 present invention proposes that the pump is provided with a return passage allowing a portion of the fluid product pressurized in the pump chamber to escape without passing through the outlet valve.
- the entire fluid dose stored in the pump chamber is not discharged through the outlet valve towards the dispensing orifice: a portion being diverted through the return passage, so that the fluid dispensed only corresponds to a partial dose of the pump.
- the return passage communicates directly or indirectly with the fluid reservoir, so that the fluid that passes through the return passage is reinjected into the fluid reservoir.
- the fluid product passing through the return passage is stored, at least for a moment, in a buffer tank which may or may not communicate with the fluid reservoir.
- the return passage creates a sealing defect at the inlet valve.
- the inlet flap is leaking.
- the return passage may be formed by the movable member.
- the return passage comprises at least one groove formed at the level where the movable member comes into contact with its valve seat.
- the return passage comprises a hole which passes through the movable member which is advantageously in the form of a disc. It is also possible to provide that the return passage is formed by the valve seat, in particular in the form of at least one groove.
- the return passage can be formed by the movable member and / or its valve seat.
- an additional return passage may be formed by the pump body.
- the additional return passage comprises a direct bore which passes through the wall thickness of the pump body and directly connects the pump chamber to the reservoir.
- the inlet valve may be of a quite conventional type.
- the pump body comprises a plunger tube connected to the inlet of the pump, the additional return passage comprising a bypass path which connects the pump chamber to the plunger tube without passing through the flap valve. Entrance. In this case, the bypass path makes it possible to bypass the inlet valve.
- the pump comprises an outer sleeve which surrounds the pump body, the bypass path extending in part between the pump body and the outer sleeve and advantageously comprising at least one internal bore which passes through the wall thickness of the pump body. pump body.
- the additional return passage can be formed in the sliding shaft.
- the invention also defines a fluid dispenser comprising a fluid reservoir on which is mounted a manual pump as defined above, the return passage, and optionally the additional return passage, allowing a portion of the fluid product. pressurized in the pump chamber to be returned directly or indirectly to the fluid reservoir.
- the spirit of the invention lies in providing a kind of leakage at the pump chamber, so that the entire dose stored in the pump chamber is not discharged through the outlet valve and the dispensing orifice, a more or less large part of this dose being redirected to another outlet which preferably communicates with the fluid reservoir.
- the leak can be achieved at the inlet valve, and / or directly at the wall of the pump chamber which communicates directly with the fluid reservoir, and / or so as to shunt the inlet valve by connecting the pump chamber directly to the dip tube.
- additional return passages can be implemented independently of the return passages at the inlet flap in certain embodiments. Separate protection could be sought for these additional return passages.
