Abstract

A hydraulic torque converter, particularly for use in a motor vehicle between the prime mover and the transmission of the power train, employs a combination of a bypass clutch with one or more torsional vibration dampers which brings about savings in space and/or in the number of parts. In addition, the torque converter can stand long periods of use and is less prone to wear, adverse influences of abruptly developing stresses and/or other undesirable influences than conventional torque converters. Furthermore, the improved torque converter employs or can employ a bypass clutch and/or one or more torsional vibration dampers simpler and less expensive than but superior to those in conventional torque converters.
