ROTARY ENGINE OPERATING ON COMPRESSED MEDIUM Russian patent published in 2012 - IPC F01C1/10 F01C17/06 

FIELD: engines and pumps.

SUBSTANCE: engine includes at least one rotor 1 and at least one stator 2, which are installed between two mutually adjacent and parallel bearing plates 3 provided with possibility of fixing drive shaft 11 of rotor 1, which is taken out to both sides and on which there fixed is rotary piston 12 placed in stator 2 chamber 21 provided with sealing cover plates 6. Piston 12 with elliptical cross section is arranged in symmetrically formed triangular chamber 21 with rounded vertexes. Each vertex is equipped at least with one channel for inlet and outlet of compressed medium so that its longitudinal axis that is coaxial to shaft 11 axis is offset relative to longitudinal axis of chamber 21 by the value of eccentricity; for that purpose, central gear wheel 7 is attached to one of plates 3 on shaft 11. In a circumferential direction of wheel 7 there uniformly arranged are three satellite gear wheels 8, which are tightly fit on pins 81 installed with possibility of being rotated in bearing plate 3 and adjacent to stator 2 by means of driving pins 23 fixed in stator 2 with eccentricity "e" in relation to axes of pins 81.

EFFECT: creation of engine with minimum number of moving elements, provided with high efficiency and operating reliability.
