Abstract
A pressure-medium actuated clutch that includes a plurality of clutch disks and a piston slidably positioned for movement toward and away from the disk to selectively engage and to disengage the clutch. A pressure chamber is provided adjacent to the piston and communicates with a source of pressurized fluid. A pilot-pressure-operated control valve is provided to control the pressure of the pressurized fluid, and a flow constriction is provided in a conduit extending from the control valve to the pressure chamber. A method for actuating the clutch is also disclosed.
