ABSTRACT:
Vibrations of the camshaft or crankshaft of a combustion engine are damped between a composite pulley which receives torque from the engine and one or more sheaves which are driven by an endless flexible member and serve to transmit torque to a pump, a blower, a compressor, a steering wheel mechanism and/or an alternator. The endless flexible member exhibits a certain amount of elasticity and the composite pulley comprises a rotary input device which is driven by the engine and a hollow rotary wheel which has a circular radially inner portion in rolling contact with the periphery of the input device. The outer diameter of the input device is smaller than the inner diameter of the wheel. The latter performs pendulum movements in response to changes in the length of the elastic flexible member.
