Cam shaft phase control mechanism for two camshafts - has control gear wheels displaced by cylinder or servo motor

摘要

Cam shaft phase control mechanism for two cam shafts in which the control gear wheels (4) are so arranged that the belt or chain sections extending from the gear wheels run parallel or almost parallel to each other. The gear wheels are displaced by, for example, a hydraulic cylinder or a servo motor (7) and as a result of the displacement the inlet and outlet cam shafts are phase adjusted. ADVANTAGE - Phase control mechanism in which number of control and diversion wheels is kept to min.
