Abstract (en)
[origin: EP0484835A1] In a dispensing device (1), the return spring (21) of a return element (20) for a discharge pump (7) and for valves (26, 30) is located separated from the fluid in a tightly sealed spring chamber (22). The fluid inlet opening (31) into the discharge pump (7) is located eccentrically with respect to the latter and opens into an external, annular pre-intake chamber (15) from which the fluid passes via an intermediate valve (30) into the pump chamber (39). As a result, contact of the fluid with metallic parts is avoided and both favourable flow paths for the fluid and a compact design of the pump are obtained. <IMAGE>
