FIG. 1 shows a schematic drawing of a device for detecting the position of a hydraulic piston-cylinder system.

Claims

1. A device for detecting the position of a hydraulic piston-cylinder system, where the hydraulic piston-cylinder system is connected to a position-detecting means which comprises a magnet and a Hall sensor, characterized by the fact that the connection between the hydraulic piston-cylinder system and the position-detecting means comprises a lever.

2. The device recited in claim 1, wherein the position-detecting means comprises at least two Hall sensors.

3. The device recited in claim 1, wherein the lever comprises one arm.

4. The device recited in claim 1, wherein the lever comprises two arms.

5. The device recited in claim 1, wherein the piston-cylinder system is part of a valve system of a hydraulic mechanism.

6. The device recited in claim 1, wherein the valve system is associated with an automatically controlled clutch.

7. The device recited in claim 5, wherein the valve system is associated with a twin clutch device.

8. The device recited in claim 1 wherein the hydraulic piston-cylinder system is an actuating element.

9. The device recited in claim 8, wherein the hydraulic piston-cylinder system is a shift cylinder of a hydraulic gear shift unit.

10. The device recited in claim 8, wherein the actuating element is associated with a continuously variable atransmission.
