Abstract

A dosing pump comprising a pump housing (48) which has a cylindrical feed piece (120) extending into the housing (48), a first hollow piston (82) in the pump housing (48) provided with a stem (68) having an axial outlet channel (98) forming a valve seat (158), a second piston in the pump housing (48) which consists of two parts (150, 190), of which one part has a piston skirt (202) and, with the tubular feed piece (120), forms an inlet valve for the liquid flowing from the container into the pump chamber (80) and of which the other part has a rod (162) interacting with said valve seat (158) to form an outlet valve. The two parts (150, 190) of said second piston interact through a return spring (240) arranged between said second piston (190) and said housing (48). The individual part of the pump reliably expose a passage between container and pump chamber. The parts can be reliably and quickly produced by an injection moulding process for plastics and it is achieved a simple and quick assembly of the dosing pump for the purpose of industrial mass production.
