Disc-type rotary engine

摘要: A rotary disc (3) having at least two radial concave portions (4) and convex portions (5) on one end is opposed the concave/convex surface to a concave/convex surface of non-rotary (2) same shape, discs is made axially slidably engaged other resiliently. Two variable volume chambers formed between concave/convex surfaces are used as set engine chambers (10,11) in which suction port disposed slope of the first chamber side that get into engagement, exhaust port is second side that surfaces (2,3) out the engagement. gas reservoir combustion (15) communicating by way compression communication channel disposed between chamber, the compression stroke conducted simultaneously, while expansion suction stroke conducted simultaneously passing through chambers.
