The upper end of each push rod has an individual drive assembly which includes a sidewise extending drive pin pivotally connected to a connecting rod reciprocated by an eccentrically mounted pivot pin protruding from the face of a crank member which is removeably mounted on a driven wheel carried by a stub shaft. A timing belt, connected over the driven sprocket, is itself driven by one of a plurality of drive wheels on a main drive shaft.
