Abstract (en)
[origin: FR2838787A1] The pump comprises a housing (10) with a pump chamber (20) defined between an inlet check valve (30) and an outlet check valve (40) and a piston (50). The piston is connected to an operating rod (60) comprising an ejection channel (65). The inlet valve comprises a non-return valve (31) and the outlet valve comprises a non-return valve (41). During activation the outlet non-return valve is forced into the closed position by the pressure of the product contained in the chamber. The outlet valve is moved to its opening position by the inlet non-return valve when the piston arrives in its distribution position. An Independent claim is included for a fluid distribution device comprising the pump.
