Actuator for frictional coupling in vehicle drive train has disengagement arrangement with pressurized medium cylinder/piston, control valve actuated by electromagnetic positioning device

摘要

The actuator has a disengagement arrangement with a pressurized medium cylinder (1) and axially displaceable piston (2), is connected via a control valve (25) to the source (28) of the pressurized medium and can be actuated depending on a control parameter and an actual value representing the piston's position. The control valve can be actuated by an electromagnetic positioning device (24).
