ABSTRACT:
A number of embodiments of valve-actuating mechanisms for reciprocating machines, such as internal combustion engines, are presented wherein the lift of the valve may be controlled. This is done by providing a pair of cams on the camshaft each of which cooperate with the same follower for commonly actuating the valve. One of the cams is radially shiftable relative to the axis of the camshaft so that it can either be brought into operative position wherein the lift is controlled by the second cam or an inoperative position where the lift of the valve is controlled by the first cam.
