<p>A radial cylinder block (2) eccentrically journalled on a shaft (15) is constrained to orbital motion within a stationary casing (1) by stabilizing eccentrics (not shown) between the cylinder block (2) and casing (1). Opposed pistons (3) within the cylinders are rigidly interconnected and eccentrically mounted on a bushing (6) rotatable about the shaft (15). The piston connecting rods (5) are slidably supported in guide bushes at the inner end of the cylinders. An arrangement of gears (7) between the bushing (6) and shaft (15) ensures that rotation of the shaft (15) and consequent orbital motion of the cylinder block (2) through its eccentrics (10) is accompanied by a counter-rotation of the bushing (6) and piston eccentrics (4) resulting in relative reciprocation of the pistons (3) within the cylinders with reduced absolute velocities of the moving parts. In particular, a two-cycle engine is disclosed with charge transfer between cylinders and having exhaust ports (14) in the cylinder walls which align periodically with matching ports (12) in the casing (1).</p> |
