A power operated clutch and gear-changing device for a motor vehicle with a gearbox (5) controlled by the driver via the clutch control on the clutch pedal (2), and having a tactile response signal provided by a signal transmitter unit (8) for the driver at the pedal (2) when the gear is engaged in the gearbox (5) comprises a valve (1) mounted in a pressure line (9) between a transmitter piston (21) mechanically connected to the pedal (2) and a receiver piston (31) for actuating the clutch (3). The valve (1) provides a flow path via the pressure line (9) from the piston (21) to the piston (31) when a gear is not engaged. and blocks flow in the opposite direction. The valve (1) is operated via a switch (23), electronic control device (7), magnetic valve (62), and the compressed air which is necessary to move the gear changing cylinders. <IMAGE> |
