A hydraulic phase shifting mechanism is described for an engine camshaft subjected to torque fluctuations during operation. The mechanism employs a magnetorheological fluid as a hydraulic pressure medium and is controlled by selective application of a magnetic field to vary the flow properties of the magnetorheological fluid.
