SYSTEMS OF INWARD-FLAW PULSED ENGINE, PUMP AND COMPRESSOR AND OF OPERATION THEREOF Russian patent published in 2010 - IPC F02B53/08 F02B55/02 F01C1/28 F01C9/00 

FIELD: engines and pumps.

SUBSTANCE: engine comprises first section of end wall, second section of end wall, first section of movable wall and second section of movable wall. Second section of end wall is separated from first section of end wall for at least partial formation of compression chamber there between. Movable wall first section is arranged between first and second sections of end wall. Movable wall first section has first section of distant edge separated from first axis of turn. Second section of movable wall is arranged between first and second sections of end wall to adjoin movable wall first section. Movable wall second section has second section of distant edge separated from second axis of turn. Movable wall second section comprises additionally cylindrical surface that pass at least partially, between second section of far edge and second axis of turn. First section of far edge of the movable wall first section can slide on cylindrical surface of the movable wall second section when movable wall first section turns forward and back about first axis of turn and movable wall second section turns forward and back about second axis of turn.

EFFECT: higher heat efficiency, reduced size and weight.
