ABSTRACT:
The disclosure is directed to a rotary engine having an annular housing and a plurality of walls disposed around the interior of the housing with adjacent walls joined by rounded corners. A plurality of sliding pistons are disposed within the interior of the housing spaced apart from one another and connected radially to a drive shaft extending through the interior of the housing along the central axis thereof. The sliding pistons having face portions adapted to slide adjacent the inner surfaces of the walls are disposed radially outward of the drive shaft. End plates disposed at opposite sides of the housing and intersecting the central axis thereof enclose the opposite sides of each sliding piston which extend to adjacent the inner surfaces thereof. The sliding pistons are guided around the plurality of walls and rounded corners of the housing chamber by cams attached to the end plates. As a sliding piston moves adjacent each rounded corner disposed between adjacent walls, a chamber is progressively formed between the face of the piston, the inner surface of the rounded corner and the end plates and then progressively eliminated as the charge is compressed. Thereafter, the compressed charge can be ignited by spark ignition or by compression ignition. Intake of an air charge as well as expansion of a compressed charge after combustion occur in the corner chambers so formed. Ports in the end plates are sequentially connected to passages extending from the sides of each piston to the face of the piston to provide a flow path with respect to each of the chambers formed between the face of the piston and a rounded corner. The ports enable the sliding pistons to control the delivery of charges and the removal of exhaust gas with respect to the chambers.
