TWO-CYCLE ROTARY-VANE DOUBLE-ACTION INTERNAL COMBUSTION ENGINE AND METHOD OF EXECUTION OF WORKING CYCLE IN SAID ENGINE Russian patent published in 2007 - IPC F01C1/63 F02B53/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to rotary internal combustion engines with rocking or rotating working members. Proposed two-cycle rotary vane double-acting internal combustion engine has body with ring space covered by end face covers and divided uniformly over circumference by at least four radial partitions, rotor with at least four radial vanes limiting, together with radial partitions of ring space, chambers formed in between and installed coaxially relative to body for rotation and oscillation around its axis, intake and exhaust manifolds, power mechanism converting rotation and oscillation of rotor into rotation of shaft with flywheel of engine. Body has two ring spaces, each closed by end face covers. Chambers of each ring space communicate through valves arranged in body between ring spaces through holes in end face covers. Valves are also installed in radial partitions. At least each of two diametrically opposite chambers of one of ring spaces communicates with two manifolds for delivering fuel-air mixture of air, and at least each of two diametrically opposite chambers of other ring space communicates with two manifolds for delivering air and at least two, with manifolds for discharging exhaust gases. Power mechanism is installed in body and is made in form of slider-crank mechanism with slide installed in guides for reciprocating and articulated with cranks installed on rotor shaft from one side and on engine shaft, from other side.

EFFECT: provision of powerful, reliable, durable engine with low fuel consumption and metal usage in manufacture and maximum efficiency of fuel combustion.
