Abstract: The invention relates to a hydraulic fluid accumulator (30) having a high-pressure chamber (32) and a low-pressure chamber (33), wherein the high-pressure chamber (32) provided with an equalizing volume (36) is disposed in the low-pressure chamber (33). Provided at the hydraulic fluid accumulator (30) is an external connection (34) for the equalizing volume (36), by means of which connection the equalizing volume (36) can be filled with a gas having a predefinable pressure.

Abstract: The invention relates to an actuating assembly (1) for the electrohydraulic actuation of displaceable elements in a vehicle. Said actuating assembly (1) comprises a pump unit (4), an electric motor (3) that drives the pump unit (4), a hydraulic fluid tank (2) and at least one valve block (5) for controlling a volumetric flow that is generated by the pump unit (4). The pump unit (1) is equipped with a control unit (20) for electrically controlling the electric motor (3) and the valve block (5).

Abstract: The invention relates to a position determination and regulation system for working devices arranged on the working arms of mobile machine-tools. Said system comprises at least one sensor and an emission/reception unit. The determination and transmission of position co-ordinates (x, y) and/or an incline (?) of the working device between the at least one sensor and the emission/reception unit are carried out in a contact-free manner.

Abstract: Gearset-drive unit (10), in particular for use in motor vehicles, comprising a drive wheel (16) that meshes with a driven wheel (22), wherein a sensor wheel (26) with a position sensor (36) that interacts with a sensor (42) to detect speed meshes with the drive wheel (16) or the driven wheel (22).

Abstract: A method for controlling an electric drive motor (10) of a motor vehicle adjusting drive by means of applying a variable voltage to it should be improved so that an EMV interference suppression can be inexpensively executed. To this end, a controllable resistor (12, 18, 20, 22) is used, which supplies the voltage applied to the drive motor (10).
