Title (EN) PISTON PUMP
(FR) POMPE A PISTON
Abstract:
(EN) A pump comprising a housing including first and second housing sections and a gasket between the first and second housing sections. The housing has a first pumping chamber, an inlet, an inlet passage in the housing leading from the inlet to the pumping chamber, an outlet and an outlet passage in the housing leading from thepumping chamber to the outlet. A pumping member is movable in the pumping chamber to pump fluid through the pump. Inlet and outlet check valves are provided in the inlet and outlet passages, respectively with each of the check valves including a movable valve element. The outlet check valve includes an outlet valve seat and a movable outlet valve element secured to the gasket at at least two spaced apart regions.
(FR) L'invention concerne une pompe comprenant un corps composé d'une première et d'une seconde section, un joint étant placé entre ces deux sections. Ledit corps comporte une première chambre de pompage, un orifice d'admission, un passage d'admission conduisant, dans ledit corps, de l'orifice d'admission à la chambre de pompage, un orifice de sortie et un passage de sortie conduisant, dans ledit corps, de la chambre de pompage à l'orifice de sortie. Un élément de pompage se déplace dans la chambre de pompage pour pomper un fluide qui traversera la pompe. Des soupapes de non retour d'admission et de sortie sont montées, respectivement, dans les passages d'admission et de sortie, chacune de ces soupapes comprenant un élément de soupape mobile. La soupape de non retour de sortie comporte un siège de soupape de sortie et un élément de soupape de sortie mobile fixé au joint en au moins deux emplacements espacés l'un de l'autre.
