Control time setter for camshaft - has switching valve supplying compressed fluid to infinitely variable adjuster setting angle of rotation between camshaft wheel and camshaft of IC engine

摘要

An adjusting element coupling the camshaft wheel (70 and the camshaft (2) is operated be a compressed medium. The flow of the latter is regulated through bores and coupling leads. The switching valve (47) forms an adjusting element with at least one non-return valve. The adjusting element is axially slidable along a shaft non-rotatably coupled to the camshaft. The adjusting element has at least two leads for reciprocal compressed medium supply between at least two piston-bore units (66,67). An electrically-operated switching valve can be used which is connected to sensors of a measurement value refiner. ADVANTAGE - Exploits irregular torque of camshaft for adjustment. Simple assembly. Low noise. Long working life.
