- the fluid dispensing pump comprises a pump body 10 in which a piston 20 slides in leaktight manner, advantageously connected to an actuating rod 21.
- the pump body 10 is generally assembled on the neck of the pump. 'a tank 1 using a fixing ring 5, which can be any, in particular snap-on, screwable, or crimp.
- the seal between the pump and the fixing ring 5 is produced by means of an annular seal 100, 200 and the sealing between the fixing ring 5 and the reservoir 1 is carried out by means of a neck seal 300.
- a pump chamber 30 is defined between an inlet valve 40, 41 and an outlet valve 50, 51, so that the pump shown in the figures is a pre-compression pump.
- the pump according to the invention includes a vent air passage 80 connecting the inside of the tank to the atmosphere.
- this vent air passage 80 is open in all positions of the pump. It advantageously extends between the upper edge 11 of the pump body 10 and the fixing ring 5.
- the annular seal 100 forms an element for filtering and / or treating the vent air.
- it is impermeable to the fluid product contained in the tank, but permeable to air, by having a filtering action on the incoming air. This saves a part, namely the filter, which simplifies manufacturing and assembly and reduces costs.
- the filter element 100 is separate from the seal 200 and is disposed between the upper edge 11 of the pump body 10 and a ferrule 60.
- This ferrule 60 is it even arranged between the upper edge 11 of the pump body 10 and the fixing ring 5, with interposition of the seal 200.
- the ferrule 60 extends inside the pump body 10 to cooperate with the piston 20 and define its rest position.
- the ferrule 60 has a radial flange 61 which rests on the end wall of the upper edge 11 of the pump body, with interposition of the filter element.
- the air passage 80 can be defined by a through bore 70 produced in the upper edge 11 of the pump body 10.
- the filtration element 100 is then preferably disposed between said upper edge 11 of the pump body 10 and said ferrule 60, completely covering said bore 70.
- said filtration element 100 may include passage means for defining an air passage part between the ferrule 60 and the annular seal 200 sealing between the pump and the fixing ring 5.
- it is the ferrule 60 which can incorporate passage means to define an air passage part.
- these passage means may include an opening 63 provided in the radial flange 61 of the ferrule 60.
- ribs and / or grooves 62 may be formed in the radial flange, on its side in contact with the seal.
- the vent air passage 80 is not open in all the positions of the pump.
- said ferrule In the pump rest position, shown in Figure 1, said ferrule not only defines the piston rest position by forming a stop for the axial movement of said piston 20, but said ferrule 60 also cooperates sealingly with said piston to seal said vent air passage 80.
- This vent air passage first passes between the actuating rod 21 and the upper end of the ferrule 60. It descends along the internal wall of the ferrule 60 to the lower end thereof, where it is closed by the piston 20 in the rest position.
- vent air passage 80 is open at this location and it extends between the pump body 10 and the outside of the ferrule 60 up to the level of the upper edge 11 of the pump body 10. Then it passes between the outside of the pump body 10 and the fixing ring 5 and enters the inside the tank (not shown in Figure 1).
- the element for filtering and / or treating the vent air 100 is also disposed between the upper edge 11 of the pump body 10 and said ferrule 60.
- the arrows schematically show l vent air flow at this location.

- the upper edge 11 of the pump body 10 may also include passage means 12, such as one or more groove (s) and / or rib (s), to define an air passage.
- the filtration element 100 is interposed between said passage means 12 of the pump body 10 and said passage means 62 of the ferrule 60.
- the filtration element 100 which can be made in the form of a radial annular element, is very easily achievable and simple to assemble, without requiring significant modification of any component part of the pump. In the particular example shown in FIGS.
- the filtration ring 100 is simply placed on the upper edge 11 of the pump body before the ferrule 60 is put in place.
- the passage means 62, 12 or 102 , respectively in the shell 60, the pump body 10 or the filter element 100 are very simple and inexpensive to produce, and it is clear that any suitable passage means are possible without departing from the scope of the present invention.
- Figures 6 to 9 show different embodiments in which the venting passage 80 extends first between the ferrule 60 and the fixing ring 5 and then between the ferrule 60 and the pump body 10.
- the pump body 10 then has a vent hole 85 opening into the tank.
- This implementation makes it possible to produce the neck seal 300 completely sealed on the pump body 10, and therefore to prevent any risk of contact of the product with the venting passage 80, the vent hole 85 being closed by the piston 20 in the pump rest position.
- the neck seal 300 may include a valve 310, visible in Figure 9, to isolate the vent hole 85.
- the ferrule 60 cooperates sealingly with the actuating rod 21, for example by means of a sealing lip 65 provided on the internal surface of the ferrule 60.
