ROTARY MACHINE Russian patent published in 2018 - IPC F01C1/44 F04C2/44 

FIELD: machine building.

SUBSTANCE: invention relates to rotary machines. Rotary machine comprises a rotor 1 connected to the shaft with the possibility of rotational movement together with it in the center of the block of pistons 4 and the base. In rotor 1, pistons 3 are mounted with the possibility of a return-turn movement. Rotor 1 with pistons 3 is arranged between two coaxially aligned with equal focal distances by the oval cylindrical surfaces 12 and 13. Bends of front outer oval surfaces 16 of pistons 3 are made coincident with the bend of the oval of inner surface 12 of outer oval cylinder 10 of block 4 from its outlet holes 20 and 21 to the minor axis of block 4 along the rotational direction of rotor 1. Bends of front internal oval surfaces 17 of pistons 3 are made coinciding with the bend of the oval of outer surface 13 of inner oval cylinder 11 of block 4 from its outlet openings 24 and 25 to the major axis of block 4 along the direction of rotation of rotor 1. On outer and inner cylinders 10 and 11 of block 4, two inlet ports 18, 19 and 22, 23 and two outlet ports 20, 22 and 24, 25 are provided. On the outside and inside of rotor 1, four variable volumes of chambers 28, 29, 30, 31 and 32, 33, 34, 35, respectively, are formed.

EFFECT: invention is aimed at simplifying the design, reducing the weight and increasing the efficiency of the machine.
