ABSTRACT:
An apparatus for cyclically actuating an actuation member in response to rotation of a cam shaft having a cam carried thereon is disclosed. The apparatus preferably includes a shaft capable of angular rotation through at least a predetermined arc, a cam follower carried by the shaft for rotation therewith and the cam follower pivotally connected to the shaft in a manner allowing reciprocation of the cam follower independent of angular movement of the shaft. The cam follower preferably having a first contact surface with the cam and a second contact surface with the valve operating mechanism. The first and second contact surfaces preferably formed as curved surfaces with a predetermined radius.
