Magnetically actuated reciprocating pump for delivering and exact dosing of hydraulic fluid from inlet to outlet area of pump, has hollow chambers of pump that are filled with fluid in currentless condition

摘要

The magnetically actuated reciprocating pump (1) has hollow chambers of a pump, which are filled with fluid in a currentless condition. A reciprocating armature piston (2) is formed as pump piston (35) and moving back by a return device and has an axially extending projection (52) of its an external contour (24) in a running in an area to pole units (13,14).
