A hydraulic unit having a hollow oil container which has a receiving space for oil between an external outer wall and an internal outer wall, and having a pump unit which comprises an electric motor and a pump which can be driven by the electric motor. Such a hydraulic unit is to be further developed in such a manner that it has only a low noise level, in which connection also sufficient cooling of the hydraulic fluid and of the electric motor should be assured. This is achieved in the manner that at least the pump, and preferably the pump unit, is included in an enclosure which is formed by the hollow oil container and at least one sound-damping element.

[ I claim:] [1.] A hydraulic unit comprising:a capsule, and a pump unit including a pump disposed in a space within said capsule;a container disposed within said capsule, said container comprising an internal outer wall and an external outer wall which encloses said internal outer wall and is spaced apart from said internal outer wall to define an oil-receiving space between said internal outer wall and said external outer wall;a sound-dampening element covering the space in which the pump is disposed; andwherein said internal outer wall is spaced apart from said pump unit to define an inner air-receiving space which separates said oil receiving space from said pump unit to accomplish a damping of sound emanating from said pump unit.
