Abstract (en)
[origin: EP0463349A1] A power cylinder (1) is proposed in which the position of a working piston (10) and the distance it covers in each case and the speed with which it covers this distance are measured by a hollow-cylindrical sensor (13, 16, 17, 18) and the result is fed to an electronic switching device. The sensor (13, 16, 17, 18) serves to pass through the aspirated air to an aspiration chamber (12) of the power cylinder (1), as a result of which the sensor can be cooled. <??>The power cylinder (1) is intended for use in motor vehicle clutches. <IMAGE>
