Abstract
A hydraulic assembly has a pressure medium container which at least partially encloses an electric motor, and a hydraulic pump which is driven by the electric motor using a simple, compact, and quiet design in a manner such that the electric motor is situated in the pressure medium container and is cooled by pressure medium without using the electric motor fan, in that the pressure medium container includes a partition which subdivides a pressure medium container interior at least partially into an intake region and a return region, and which maintains a certain level of pressure medium in the return region, and the electric motor is located in the return region of the pressure medium container.
