Oscillating motor phase adjuster for changing control time of valve controller of four-stroke engine, has reverse spring device arranged in pressure chamber that is subjected to pressure, in axial direction

摘要

The adjuster (1) has a housing that is torque-proofly coupled to a gear wheel (2) and comprising radially inward pointing bars. An impeller torque-proofly coupled to a camshaft, has a blade that is limitedly guided into two reverse channel openings that are formed in opposite rotation directions. A reverse spring device is arranged in a pressure chamber that is subjected to pressure, in an axial direction and assigned in both rotation directions.
