ABSTRACT:
A valve mechanism has a rocker arm comprising a rocker arm member rocked by a cam and an actuating arm member operatively engaged with the rock arm member for operating a stem of a valve. A sleeve is rotatably and slidably mounted on a rocker-arm shaft. The rocker arm member is slidably engaged with splines of the sleeve, and the actuating arm member has splines corresponding to the splines of the sleeve and is slidably engaged with a cylindrical portion of the sleeve. A pistion is slidably mounted on the rocker-arm shaft adjacent the sleeve, and shifted to shift the sleeve to engage the splines thereof with the actuating member. The sleeve is held by a stopper at a disengagement position and an engagement position with the actuating arm member respectively.
