Abstract
A barrel engine has a housing with a longitudinal bore with a pair of spaced apart bearing surfaces. An output shaft is disposed in the bore and has an outer surface with engagement elements. A cam plate has a central portion and a cam portion. The central portion has an outer surface with a pair of spaced apart bearing surfaces and a bore with an inner surface with engagement elements. The cam plate is received on the output shaft with the engagement elements on the inner surface of the cam plate bore being mechanically coupled to the engagement elements on the outer surface of the output shaft such that the shaft and cam plate are coupled for rotation and the cam plate is longitudinally slidable with respect to the shaft. The cam plate is disposed such that the bearing surfaces are generally aligned with the bearing surfaces of the bore.
