OSTI ID:5107394
A valve mechanism for an automotive engine having a rocker arm comprising a rocker arm member rocked by a cam and an actuating arm member operatively engaged with the rocker arm member for operating a stem of a valve is described comprising: a sleeve rotatably and slidably mounted on a rocker-arm shaft and having splines on a periphery thereof and a cylindrical portion adjacent the splines. The rocker arm member has splines and slidably engaged with the splines of the sleeve. The actuating arm member has splines corresponding to the splines of the sleeve and slidably engaged with the cylindrical portion of the sleeve at a disengagement position. A piston is slidably mounted on the rocker-arm shaft adjacent the sleeve; and hydraulic means are for applying oil to the piston so as to shift the sleeve to an engagement position to engage the splines thereof with the actuating arm member. A spring is provided between the cylindrical portion and a shaft holder for shifting the sleeve from the engagement position to the disengagement position; and stopping means hold the sleeve at the disengagement position and the engagement position respectively.
