Title: ELECTRIC GEROTOR PUMP AND METHOD FOR PRODUCING SAME
Abstract:
An electrically driven gerotor pump has a gerotor (3) which comprises a stationary outer gerotor element (31) with an inner toothing (33a) that is axially delimited by two chamber walls (13a, 13b), wherein each chamber-forming foot section of the inner toothing (33a) is paired with a pressure valve (4) which is connected to the outlet (16). The gerotor also comprises an inner gerotor element (30) with an outer toothing (33b) which is guided in the outer gerotor element (31) in a circumferential manner on an eccentric section of the shaft (2) and is mounted in a rotatable manner so as to mesh with the inner toothing (33a).
