ABSTRACT:
A barrel-type reciprocating machine having a block with a shaft journaled through its center with the ends of the shaft offset at an oblique angle. A pair of wobble spiders are attached to the oblique crank end of the shaft and are in turn attached to an output shaft. A plurality of cylinders are angularly spaced around the shaft parallel to the axis of rotation of the shaft. Each cylinder has a pair of opposing pistons and a plurality of intake and exhaust ports which are open and closed by the opposing pistons. Semi-circular concentric intake and exhaust manifolds surround the cylinders and communicate with the ports leading to the cylinders. The intake manifold has a plurality of coolant tubes passing through the wall of the intake manifold and into the cavity for cooling the intake air passing through the manifold into the cylinder. The coolant tubes traverse a circuitous path through the manifold and pass back out through the wall of the intake manifold to hose fittings. A suitable refrigerant is circulated through the coolant tubes when the engine is operating to cool the intake air entering the cylinders, the cylinder itself, and the intake piston, thus substantially increasing the thermal efficiency of the engine.
