The clutch (1) has at least one piston/cylinder unit with a cylinder filled with pressure medium, a charge-able piston (28) to operate the clutch, and a medium supply unit with valve. The cylinder is almost pressure-less at the start of the operation, and quicker filling is achieved by using increased pressure, followed by slower filling after the pressure within the cylinder has reached a set level, or after a set time period has lapsed. The increased pressure is generated in a pressure chamber (27) in front of the cylinder using a proportional valve.
