Abstract
A cam shaft assembly comprises a first coupling between a drive collar rotatable with a driving shaft and an annular disc at a first position spaced from the shaft axis, and a second coupling between the disc and said hollow cam at a second position angularly spaced from said first position with respect to the shaft axis. The first and second couplings are so spaced from the shaft axis that they are at varying distances from the axis of the disc during operation. Each of the first and second couplings has a movable connection with the disc to permit the variation in its distance from the axis of the disc. The disc is rotatably supported in a disc housing. A control rod is mounted for rotation and has an eccentric control cam which controls movement of the disc housing. A pivot shaft extends through the disc housing for allowing movement of the disc housing following the eccentric control cam in which said plurality of hollow cams are disposed.
