FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to engines with rocking pistons. Proposed engine has hollow cylindrical housing with longitudinal partitions and operating shaft with operating and delivery vanes. Spaces in form of operating and delivery chambers are formed at both sides of each partition. According to invention, operating and delivery chambers are arranged opposite to each other in diameter relative to housing axis. Capacity of operating chambers is smaller than capacity of delivery chambers, and height of operating vanes is smaller than height of delivery vanes. Bypass channels connecting operating and delivery chambers are made on shaft at both sides at base of each delivery vane. Each partition has holes for nozzles, and antifriction bearings of operating shaft are built into end face covers of housing.
EFFECT: increased efficiency at reduction of mass and dimension characteristics.
