ROTOR-VANE INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 2016 - IPC F02B55/02 F02B55/08 F01C1/344 

FIELD: engines.

SUBSTANCE: invention relates to rotary-vane internal combustion engines. Working surface of housing in first version of engine consists of four equal-angle areas of surface. Two sections of an arc, symmetrical about vertical axis, have different radii, and adjacent sections of arcs have radii such that value of resultant diameter remains invariable. A rotor is placed in area of ​​a quarter circle of least diameter. On both ends of the rotor there are two U-shaped grooves in opposite directions and crosswise to each other. Two holes are drilled in each groove for inserting helical springs which press vanes inserted in said grooves. Vanes are U-shaped. Working surface of housing in second version of engine is divided relative to centre into four angular sectors. Central sectors of generatrix are in form of two, symmetrical relative to vertical axis, circular arcs with angular size of approximately 80 degrees each. Two lateral sectors are made in form of arcs of an ellipse with an axis ratio of about 1/1.2. A rotor is placed in area of central circle with a diameter, with minimum clearance less than diameter of generatrix of the housing.

EFFECT: technical result is high specific power and easy manufacture of engine.
