ABSTRACT:
An actuator cylinder for the engagement and release of the friction clutch of a motor vehicle is described. The actuator has a device to indicate clutch engagement position, which is located outside the cylinder. A piston is disposed within the actuator cylinder. The piston has an actuator rod which extends through a cylinder end to operate a clutch. The device to detect the engagement position of the clutch is designed to adjust to the range of movement of the piston, which range of movement changes with clutch wear. The detection device is a displacement transducer. A housing, in which the transducer is mounted, moves as the range of motion of the piston changes with clutch wear. A rod or sensor mounted on the piston both interacts with the transducer to indicate the clutch engagement position and moves the housing of the transducer.
