Abstract (en)
[origin: WO2010010094A2] The invention relates to a piston engine the piston of which is designed as a dual piston swivel plate (15) having effective working surfaces on both sides which swivel plate can be swiveled about a swivel axis (14) between two lateral walls (5, 6) of a working chamber (2) that substantially has the shape of a segment of a circle, said lateral walls being arranged at an angle to each other and having respective inlet and outlet valves (22, 23; 24, 25). The swivel plate is further connected to a crank mechanism which is arranged in a crankcase that is sealingly separated from the working chamber (2). The dual piston swivel plate (15) is connected to a connecting rod (16) which is designed as a connecting loop and has a guide groove (17), via a rotating cylinder (9) connected to the swivel plate. Two or more working chambers can be arranged on the periphery or one after the other on one and the same rotating cylinder which is actuated via the connecting rod. When the crankshaft is rotated about 180°, the respective dual piston swivel plate performs a swivel motion and at the same time the working strokes intake/work and compression/exhaustion. The efficiently working and versatile piston engine has a simple and compact design.
