This invention relates to a precompression pump for spraying a liquid, comprising: a pumping chamber (2) containing a first piston (7) attached to an operating mechanism (6), this piston being held by a first spring (9); a precompression chamber (5) equipped with a second piston (10) held by a second spring (11), the precompression chamber communicating with the pumping chamber, their axes of symmetry being offset; a supply channel (4) equipped with a check valve (4a, 15) opening into the pumping chamber; a distribution component (17) equipped with a nozzle (20) and a distribution channel (18) connecting the nozzle to the precompression chamber, the latter including a means for opening and closing the said distribution channel so that the communication will be closed in the pump's rest position and opened when the operating mechanism is moved, the means then opening a passage between the precompression chamber and the distribution channel.
L'invention se rapporte à une pompe à précompression pour pulvériser un liquide, comprenant: - une chambre de pompage (2) contenant un premier piston (7) associé à un organe de manoeuvre (6), ce piston étant en appui contre un premier ressort (9); - une chambre de précompression (5) munie d'un second piston (10) en appui contre un deuxième ressort (11), la chambre de précompression communicant avec la chambre de pompage, leur axe de symétrie étant décalé; - un canal d'alimentation (4) muni d'un clapet (4a, 15), débouchant dans la chambre de pompage; - un élément de distribution (17) muni d'une buse (20) et d'un canal de distribution (18) reliant la buse à la chambre de précompression, cette dernière comportant un moyen de mise en communication et de fermeture dudit canal de distribution, afin que la communication soit interrompue en position de repos de la pompe et que la communication soit établie sous l'action de l'organe de manoeuvre, le moyen libérant alors un passage entre la chambre de précompression et le canal de distribution.
