Abstract (en)
[origin: EP2143935A1] The pump unit has a pump housing (14) with a pump housing opening (16), and a drive shaft (24) for driving the pump unit. The drive shaft is arranged in the housing opening. A pump cover (15) closes the housing opening in a fluid-tight manner. A radially circulating spring element (44) e.g. disk spring and compression spring, axially lies at the pump cover. The spring element is designed such that the pump cover is pressed at the pump housing in an axial direction by the spring element. A retaining ring (46) e.g. snap ring, fixes the spring element in the axial direction.
