ROTARY PISTON ENGINE Russian patent published in 2017 - IPC F02B55/02 F01C1/344 F01C19/04 

FIELD: engines and pumps.

SUBSTANCE: in the rotor-piston internal combustion engine, in cross-section, rotor 2 is a Reuleaux triangle and located eccentrically in a cylindrical cavity of stator 1. In the tops of rotor 2 in the grooves, U-shaped rectangular pistons 3, 4, 5 are placed. Pistons 3, 4, 5 are made with longitudinal slots. Wear resistant inserts are placed in the tops of pistons 3, 4, 5, 6. The volumes between the inner surface of pistons 3, 4, 5, rotor 2 and side covers form unchanged total oil volume where constant pressure is maintained by oil pumping. Nozzle 17 is placed in stator 1 in the second half of the third quarter of stator 1 if we start counting from the vertical symmetry axis of the working hole of stator 1 clockwise. Plugs 8, 9 are placed in the first and the fourth quarters of stator 1. Exhaust holes are placed in the second half of the second quarter of stator 1. Holes for injecting compressed air are placed in the first half of the third quarter or on the vertical symmetry axis of stator 1. The hole for oil injection into the internal volumes of the pistons is made in the end cap and placed in the first half of the third quarter of stator 1.

EFFECT: increased technological design of the rotary-piston engine, increased engine reliability and durability.
