ABSTRACT:
In a torque converter equipped with a fluid operated lock-up clutch to provide either a fluid or a rigid mechanical connection between an input and an output shaft, the reactor member is arranged for movement along the converter axis between a working and a retracted position by a fluid operated actuating piston. Upon engagement of the lock-up clutch, the reactor member simultaneously travels from the working to the retracted position, in which latter position the reactor member closes the flow path in the impeller member, in order to minimize power loss incurred by the hydraulic fluid.
