GEAR-CRANK PISTON MACHINE Russian patent published in 2022 - IPC F01B9/04 

FIELD: engine building.

SUBSTANCE: invention relates to engine building, production of power plants, compressors, pumps. A gear-crank piston machine contains case 10, in which cylinders are fixed. In case 10, support bearings, output shaft 8, two identical gear wheels 1 and 3, binding gear wheel 2, rollers, 6, crank 4, pistons 5 are installed. Wheels 1, 3 have the same number of gears. On wheels 1, 3, pins 9 are installed, on which rollers 6 are put, synchronized relatively to each other at an angle of 90 degrees. Wheel 2 is located between wheels 1, 3, rigidly fixed with shaft 8, and it is a gearbox. Crank 4 is rigidly connected to pistons 5 located opposite. Crank 4 has two radial grooves. Wheels 1, 3, alternately rotated by rollers 6, engage with crank 4 by grooves and move crank 4 with pistons 5. Crank 4 is reciprocatively moved, closing a kinematic circuit.

EFFECT: invention is aimed at an increase in the reliability, reduction in friction, reduction in energy consumption, increase in performance of operation, reduction in dimensions, simplicity of manufacture.
