Beschreibung
Zusammenfassung:	An electromotor and hydraulic pump unit with a sealed housing has a common drive shaft projecting with one end into a balancing pressure chamber in the pump stator. Pressure fluid flows along the shaft into a cavity of the housing in which the electromotor and the other shaft end are located so that the motor is cooled, the shaft bearings in the cavity lubricated by the pressure fluid, and the axial force acting on the bearings is reduced.
