いは必要な電気導管のために問題である。BACKGROUND OF THE INVENTION Hydraulically actuated drive elements are used, for example, in the actuation of friction clutches in motor vehicles which act between the drive machine and the transmission mechanism. In other words, a friction clutch that operates automatically is known, for example, from DE 4011 850 A1. This clutch can connect / disconnect the clutch via an operating mechanism having a disengaging bearing and a clutch coupling box fitted therein. The operating mechanism is again operated via an adjusting unit in the form of a pressurizing cylinder, the drive element being connected to the pressurizing medium circuit via a drivable pressurizing distribution valve. Furthermore, an electronic control unit is provided for controlling the distribution valve of the pressurized medium circuit in accordance with various characteristic quantities in order to coordinate the intervention of the corresponding clutch via the pressure regulating unit. Such characteristic quantities are, for example, the engine speed, the position of the throttle valve, the operation movement of the clutch, or the intervention state of the clutch.
In the known operating device, the actuation of the clutch or the intervention of the clutch is detected by means of a potentiometer which is arranged directly on the adjusting unit, which potentiometer detects and corresponds to the movement or position of the adjusting unit. The quantity of electricity is introduced into the electric control device. In a particular use case of such a pressure regulating unit, the direct placement of the position or distance measuring detector is problematic due to the occupied space or due to the required electrical conduit.
