An oil management system is provided to compensate for the undesirable pressure applied by the fluid in a piston chamber induced by fluid actuated pistons and centrifugal forces. An oil management system comprises a plurality of disk bundles(12,14), pressure chambers, and balance chambers(62,70). The disk bundles are disposed to transmit a torque from a torque input to an output shaft. The pressure chambers are associated with the respective disk bundles. Each of the pressure chambers has a pressure piston for reversibly operating the disk bundle so as to transmit a torque from the torque input to the output shaft when the pressure chamber is pressed by the supply of fluid. The balance chambers are associated with the respective pressure pistons, and have a fluid supply. The balance chambers are arranged in such a manner as to apply a compensating hydraulic pressure opposite to the hydraulic pressure of the first pressure chamber, with respect to the pressure piston. The balance chambers fluid-communicate with the fluid supply. The fluid supply is arranged to provide a flow to the balance chambers under the low speed condition which is effective for maintaining the compensating hydraulic pressure in the balance chamber for compensating for the hydraulic pressure in the first chamber induced by a centrifugal force. |
