Abstract
A cylinder valve operating system for a variable displacement internal combustion engine having poppet valves includes a cam arm driven by a camshaft and a valve arm selectively driven by the cam arm. A valve arm positioner, which may be hydraulically cushioned, adjustably maintains the valve arm in contact with the valve stem when the valve arm is not being driven by the cam arm, in order that the valve arm will be accurately located for speedy and precise linkage of the cam arm to the valve arm.
