Abstract

The clutch e.g. for motor vehicles has a piston (35) which moves axially within a hollow body (10). When hydraulic pressure is applied to the piston the clutch plates (44) are brought into contact and the system transmits torque. When hydraulic pressure is removed, the coil spring (62) retracts the piston releasing the clutch plates. The piston has an annular projection (76) which moves away from the end face of the shaft (19) to form a passage (70) for cooling or lubricating oil to reach the clutch plate assembly when the clutch is engaged. When the clutch is disengaged the ring (75) seats on the end of the shaft closing off the oil system.
