Abstract: A hydraulic unit with open-loop and closed-loop control of brake pressure in a brake circuit of an electronically slip-controllable braking system of a motor vehicle includes a pump housing, a motor for driving a brake pressure generator, and an electronic control device for controlling the motor in line with demand. The motor and the control device are disposed on opposite sides of the pump housing, and a shaft bore extending all the way through is formed therebetween, in which shaft bore a motor shaft which can be rotationally driven is disposed. A sealing apparatus seals the shaft bore with respect to an interior of the electronic control device. A sealing apparatus which comprises an insertion seal is disposed on the pump housing in a seal socket and a mechanical preloading force is applied by a preloading apparatus. A method of assembling the hydraulic unit is also provided.

Abstract: The invention relates to an axial spring element (6) having two peripheral ring elements (61, 62) that are spaced from one another in the axial direction and are connected to one another in a spring-elastic manner, wherein at least one of the ring elements (61) comprises one or more retaining elements (64) in order to brace the spring element with a rotor (5) and thereby hold the spring element on the rotor (5).

Abstract: In an electromechanical energy converter having an outer body and an inner body, which are mounted movably relative to one another about an axis of rotation, an outer body according to the invention surrounds an annular structural element, a permanent magnet and a support ring which is received concentrically in the structural element. The support ring comprises a recess to receive the permanent magnet, and the recess has a boundary surface which extends parallel as to a radius of the axis of rotation.
