The light and short piston-rod drive pairs form four expansion spaces simultaneously in each cylinder. The piston rod bearing bosses are rotatably mounted with the uniform revolving finely toothed double planetary gearwheel on the pitch circle crankshaft, as a result of which the piston rods are guided backwards and forwards positively in a straight line. Fig. 1 shows an 8-chamber 4-stroke radial engine where the cylinder pairs are offset by 70 DEG relative to one another and, via the planetary drive, produces an X-shaped stroke movement with an assymetric ignition sequence. Fig. 2 shows the three piston rod pairs, crossed in a triangle, of a 2-stroke radial engine controlled by means of the valves and scavenged by the high-pressure air from the blower, this engine pumps with the valves of the inner piston chambers as compressors or these can jointly form a 12-expansion chamber drive motor and, in the case of economy driving, the six co-operating inner-piston driving chambers can then be switched off. The reduced mass movements of the narrow piston-rod pairs float backwards and forwards between the explosion pressure drop and transmit only the converted torque outwards without damaging bearing loads and lateral piston friction pressures. This lightweight compact radial boxer engine compressor has a large volume and is suitable for high combustion force pressures. <IMAGE>
