Variable valve control system with vibration damper for engine

摘要

The system has an inlet element (11) having a rotary moment and an outlet element (12) driven by a valve. A piston (32) transmits the rotary moment of the inlet element to the outlet element. A damper covering (49) is fixed to the inlet element and has a guide recess (61) stretching in the peripheral direction of the covering and which is filled with viscous fluid. A damper housing (35) is fixed on the outlet element and forms a damper chamber (48) having a projection (60) arranged in the guide recess. A slot (74) acts as an opening between the outer face of the projection on the damper housing and the inner face of the guide recess. The guide recess limits the movement of the projection so that the forward end of the piston does not come into contact with damper housing.
