The device has a hydraulic drive element (1) movably mounted in a housing and an arrangement for determining the position of the working element with respect to a point fixed with respect to the housing. The position measurement arrangement contains several resistance elements (5) distributed along the path of motion of the working element for changing its motion resistance and a sensor which detects a parameter varying with motion resistance, esp. a hydraulic pressure value An Independent claim is also included for a hydraulic drive unit forming part of the device. |
