Actuator

Abstract

Actuator (1) with a housing (2) having an interior housing space in which a drive motor (20) and a piston-cylinder unit (24, 31) and a pressure medium reservoir (15) are arranged, wherein the piston-cylinder unit (24, 31) has a cylinder space (31) with a piston (24) displaceably arranged therein, wherein the cylinder space is part of the interior housing space and can be sealed by a seal (32) connected to the piston (24), wherein the pressure medium reservoir (15) forms a common volume with the interior housing space and substantially the entire interior housing space is filled with the pressure medium fluid (18) during operation of the actuator (1).

AN_WPI: 201561108G TI_WPI: Actuator, particularly a hydraulic actuator, for actuating a clutch or transmission of a motor vehicle, has a housing that comprises interior, inside which driving motor, piston-cylinder unit, and pressure medium reservoir are arranged AB_WPI: NOVELTY: The actuator (1) has a housing (2) that comprises an interior, inside which a driving motor (20), a piston-cylinder unit, and a pressure medium reservoir are arranged. A piston-cylinder unit has a cylinder chamber (31), inside which a piston (24) is moved and which is part of the interior of the housing. The cylinder chamber is sealed by a seal (32) that is connected to the piston. A pressure medium reservoir (15) and the interior of the housing form a common volume. USE: Actuator, particularly a hydraulic actuator, for actuating a clutch or transmission of a motor vehicle. ADVANTAGE: The actuator has a housing that comprises an interior, inside which a driving motor, a piston-cylinder unit, and a pressure medium reservoir are arranged, and hence ensures simple structure of the actuator.
