PNEUMATIC ROTARY ENGINE Russian patent published in 2016 - IPC F01C1/344 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in pneumatic engines. Pneumatic rotary engine comprises stator 1 with covers 2 and inlet and outlet holes, eccentrically installed rotor 5 and blades in the form of rollers arranged in radial slots 8 rotor 5. Rollers are equipped with permanent magnets interacting with internal surface of stator 1. Rotor is made of nonmagnetic material. Permanent magnets rollers are oriented so that rollers are pushed off from each other. At the ends of each roller there through a hole connected with the side surface of the roller.

EFFECT: higher specific power of engine due to reduced friction losses of blades on internal surface of the stator covers.
