Abstract: A pneumatic brake servo for motor vehicles having a servo housing, the interior of which is divided into at least one working chamber and at least one vacuum chamber by at least one axially movable wall which can be loaded with a pneumatic differential pressure, having a control valve which controls the differential pressure and is arranged in a control housing for connecting the working chamber to the vacuum chamber or to atmosphere. The movable wall includes a diaphragm plate and a rolling diaphragm, and the working chamber is sealed by a sealing ring which bears against the control housing and which is clamped in the radial direction in relation to a longitudinal axis of the brake servo. An actively loaded area of the movable wall is reduced by division of the working chamber into a prechamber and a main chamber to avoid stick/slip effects and reduce disruptive noises.

Abstract: An adjusting device for rotor blades of a wind power plant is disclosed. An AC motor is provided for adjusting the angle setting of the rotor blades. An input serves for receiving an input alternating current. A frequency converter is provided for generating a second alternating current having a second frequency, wherein the second alternating current drives the AC motor. Additionally, a DC voltage source and an inverter are provided for converting the voltage provided by the DC voltage source into an alternating current for the AC motor. The inverter is thereby separated from the frequency inverter.
