On connait déjà des pompes de dosage de ce type Elles se composent d'un grand nombre de pièces unitaires dont l'assemblage coûte cher Dans de telles pompes qui, en général sont adaptables à des récipients de dimensions déterminées remplis de liquide à refouler et qui doivent délivrer une quantité dosée de liquide par élévation du piston, la chambre de dosage est réduite en volume par enfoncement du piston du type 1 outon-poussoir de sorte que l'air contenu dans cette chambre, ou la matière à expulser par l'intermédiaire de la soupape de retenue, s'échappe vers l'extérieur En faisant jouer le ressort du piston en sens inverse, il apparait une dépression dans ladite chambre, entre le piston et la cloison séparatrice du boîtier, de sorte que, par montée dans le tube ascendant qui plonge dans le récipient en liaison avec l'atmosphère, il s'écoule une quantité déterminée de liquide dans la chambre de dosage Cette quantité est refoulée à chaque fois vers l'extérieur lorsqu'on enfonce le piston Dans les dispositifs connus, on prévoit non seulement sur le tube ascendant mais aussi sur le piston une  Dosage pumps of this type are already known. They consist of a large number of unitary pieces whose assembly is expensive. In such pumps which, in general, are adaptable to containers of determined dimensions filled with liquid to be discharged and which must deliver a metered quantity of liquid by raising the piston, the metering chamber is reduced in volume by depressing the piston of the type 1 outon-pusher so that the air contained in this chamber, or the material to be expelled via of the check valve, escapes to the outside By playing the spring of the piston in the opposite direction, there is a depression in said chamber, between the piston and the partition wall of the housing, so that, by rising in the ascending tube which plunges into the container in connection with the atmosphere, a certain quantity of liquid flows into the metering chamber. This quantity is discharged each time to the When pushing the piston In the known devices, not only on the ascending tube but also on the piston

Les pompes de dosage du type précité constituent des pièces fabriquées en grande série qui sont mises en place sur les récipients les plus divers Il convient donc d'en réduire le coût au maximum. Le but de l'invention est précisément de proposer une pompe distributrice de liquide du genre susmentionné mais qui soit  The metering pumps of the aforementioned type are mass-produced parts which are placed on the most diverse containers. It is therefore necessary to reduce the cost to the maximum. The object of the invention is precisely to propose a liquid dispensing pump of the above-mentioned kind but which is

La nouvelle pompe selon l'invention est essentiellement caractérisée en ce qu'elle comporte une garniture de soupape monobloc munie de clapets à action ressort dans le piston, ainsi qu'un autre ensemble unitaire de clapets de soupape à l'entrée du tube ascendant dans la chambre de dosage. Conformément à un mode d'exécution préférentiel, une telle pompe comprend une soupape à clapets, logée dans un compartiment  The novel pump according to the invention is essentially characterized in that it comprises a one-piece valve seal fitted with spring-loaded valves in the piston, as well as another unitary set of valve valves at the inlet of the ascending tube in the dosing chamber. According to a preferred embodiment, such a pump comprises a valve with valves, housed in a compartment
