ROTARY-PISTON THREE-PHASE INTERNAL COMBUSTION ENGINE Russian patent published in 2010 - IPC F02B55/02 F01C1/00 F01C17/06 

FIELD: engines and pumps.

SUBSTANCE: rotary-piston three-phase internal combustion engine has construction versions for working cycles per one or two rotations of crankshaft. Engine includes a fixed housing with three-sided working chamber made in it, gas distribution mechanism and axisymmetrical rotor-piston with heads with cylindrical surfaces. Working chamber is made in the form of a figure of fixed width and which is formed with radii of associated arcs. Engine drive mechanism is equipped with two pairs of rollers installed on edges of rotor-piston coaxially to cylindrical surfaces of heads and interacting with cylindrical working surfaces of sectors on crankshaft. Rotor-piston is located inside working chamber and its central hole is installed on eccentric bushing. The latter is arranged on crank pin of outlet crankshaft. Eccentricity of crankshaft and eccentric bushing is chosen as per ratios in accordance with versions of the design: or where d - diametre of the circle inscribed in equilateral triangle with corners in the centres of associated arcs; K - eccentricity of crankshaft; E - eccentricity of eccentric bushing.

EFFECT: improving reliability, service life and power at decrease of weight and dimensions parametres, and simplifying the design.
