A fluid pump (20) comprises a dispenser body (22), closure cap (54), seal assembly (34), and priming check valve (88). The dispenser body (22) has a pump (24), discharge port (102), and a discharge path (76). The closure cap (54) is connected to the dispenser body (22) and closes the mouth of the container (56). A first portion (60) of seal assembly (34) prevents leakage between closure cap (54) and the mouth of the container (56) when the closure cap (54) closes the mouth of the container (56). A second portion (62) of the seal assembly (34) has an intake port (78) for fluid communication with liquid in the container (56). The second portion (62) and dispenser body (22) define an intake path. A check valve (88) in the intake path permits fluid flow from the intake port (78) to the pump (24) and for checking fluid flow from the pump (24) to the intake port (78). The second portion (62) of the seal assembly (34) comprises at least part of the check valve (88).
L'invention concerne une pompe (20) comprenant un corps distributeur (22), un bouchon (54), un ensemble joint (34) et une soupape de retenue d'amorçage (88). Le corps distributeur (22) possède une pompe (24), un orifice d'évacuation (102) et une voie d'évacuation (76). Le bouchon (54) est raccordé au corps distributeur (22) et ferme le goulot du récipient (56). Une première partie (60) de l'ensemble joint (34) empêche le liquide de fuir entre le bouchon (54) et le goulot du récipient (56). Une seconde partie (62) de l'ensemble joint (34) comporte un orifice d'admission (78) conçu pour permettre la communication avec le liquide dans le récipient (56). La seconde partie (62) et le corps distributeur (22) forment une voie d'admission. Une soupape de retenue (88) placée dans la voie d'admission permet l'écoulement du fluide de l'orifice d'admission (78) à la pompe (24) et le contrôle de l'écoulement de fluide de la pompe (24) à l'orifice d'admission (78). La seconde partie (62) de l'ensemble joint (34) constitue au moins une partie de la soupape de retenue (88).
