ABSTRACT:
A device for switching valve operation modes in an internal combustion engine with a rotatable camshaft having cams integral therewith, valves disposed in intake or exhaust ports of the combustion chamber and normally urged closed by a spring, and the valves being openable by the cams through a plurality of rocker arms disposed adjacent to each other for imparting the cam lifts to the valves. A coupling mechanism selectively connects and disconnects the rocker arms by means of pistons in aligned guide holes in the rocker arms movable between positions to either extend across the adjacent sides of the rocker arms or be aligned with such sides. A solenoid is provided in one rocker arm and surrounds a piston to selectively cause movement of that piston. Springs urge the pistons to the position controlled by the solenoid.
