Vane cell pump has pump chamber formed to prevent catching of sliding element on bounding edges of at least one fluid inlet opening of base plate during pump operation

摘要

The pump (1) has a mounting plate (15) to which a housing (12) with an electrical drive unit is attached, a pump chamber with a base plate (4) with at least one fluid inlet opening (24), a pump ring (7) and a cover plate (8) and a rotor (5) with a number of sliding elements (6) rotatably arranged within the pump chamber. The pump chamber is formed so that during operation of the pump catching of a sliding element on the bounding edges of the at least one fluid inlet opening of the base plate can be prevented.
