ABSTRACT:
An engine valve mechanism including a rocker arm mechanism having a cam actuated arm which is swingable actuated by a cam and a valve actuating arm which functions to open to the engine valve when it is swingably moved. A plunger is provided on one of the arms for an axial movement and extends toward the other arm. A locking plate is movable between a locking position and retracted position. In the locking position, the locking plate locks the plunger against the axial movement so that the swinging movement of the cam actuated arm is transmitted through the plunger to the valve actuating arm to thereby make it possible to actuate the valve in response to a rotation of the cam. In the retracted position, the locking plate releases the plunger so that the swinging movement of the cam actuated arm is not transmitted to the valve actuating arm.
