Abstract
The invention engine comprises a compressor with a rotary piston in a cylinder bore in a stator and a U-shaped box-like combustion-expansion compartment, conveniently called a U-box, immediately above and riding on the rotary piston, the U-box and the compressor unit contained between the same parallel end walls. The rotary piston is eccentrically mounted on a shaft which is concentric with the cylinder bore and is supported in bearings in the end walls. A wiper blade is fitted in a groove across the piston head to yieldably sweep the cylinder bore to generate a suction stroke behind it, drawing in air via a one-way inlet port in the perimeter of the cylinder, and a compression stroke ahead of it to compress the air drawn in during the preceding suction stroke. The U-box is in the shape of a rectangular plate bent upward at two places to form two parallel vertical sides of equal height and a base plate between them. It is closed on its ends by the end walls, between which it reciprocates; it is closed above by a fixed casting to form a compression head; and its vertical sides recede into channels in the stator as the piston forces it upward on the upward compression stroke, the pis…
