Abstract:
An engine variable valve operating apparatus includes a cam switching mechanism having a switching drive shaft. When the switching drive shaft is longitudinally moved, a cam mechanism advances and retracts a switching pin. When the switching pin is advanced to engage in a lead groove formed around a cam carrier and the cam carrier is axially moved while rotating, cam lobes around the cam carrier are switched to act on an engine valve. An actuator for the switching drive shaft includes an actuator drive body which is linearly reciprocally movable and is coupled to a longitudinal end of the switching drive shaft to axially move the same. The above arrangement enables the cam switching mechanism and the actuator mechanism to be simple and compact in structure for preventing the engine from becoming large in size.

Claim (Index 3):
The variable valve operating apparatus according to  claim 1 , wherein the actuator is a hydraulic pressure actuator reciprocally moving the actuator drive body under hydraulic pressure.
