ABSTRACT:
The apparatus is particularly provided for an overhead cam type engine in which cam lobes directly act upon the upper side of rocker arms. A hydraulic piston is formed under a floating stud pivotally supporting the rocker arm thereon for cooperation therewith and is hydraulically operated through a solenoid-operated directional control valve between a normally operating position and a locking position in which an engine valve is deactivated. The control valve is actuated from an electronic system to render one or more cylinders inactive for certain engine power output.
