Abstract
A valve-actuating variable cam for a reciprocating machine is disclosed. The cam comprises a camshaft journalled for rotation by said machine and driven in timed relationship with said machine, a first cam fixed upon said camshaft and rotatable with the camshaft, and a second cam fixed for rotation with the camshaft and moveable relative to the first said cam in a direction radial to the axis of rotation of the camshaft. A shift rod is slidably mounted within the cam shaft, the shift rod having a drive surface thereon driving a key element. The key element is at least partially positioned within and engages at least the second cam. The shift rod is moveable between a first position in which the first cam engages a valve or similar element, and second position in which the key pushes the second cam radially outwardly and the valve engages the second cam.
