Abstract
A yoke with an elliptical slot in it is driven by a reciprocating motion in guide by a circular cam carried off-center to a rotating shaft. The minor axis of the ellipse is equal to the cam diameter and is parallel to the direction of reciprocating motion. The major axis is equal to the cam diameter plus twice the off-center distance of the cam. The yoke may be attached to a piston in a compressor by a connecting rod, or may be formed as a portion of the piston.
