FIELD: machine engineering.
SUBSTANCE: rotary-blade machine comprises a stationary housing 1 with an axle 2 on which the rotor 3 is rotated and connected with eccentrically located additional axle 4, around which the blades 5 are movably located with formation of variable inter-blade space. There is a working chamber 6 located inside the blade 5 and divided into two outer and inner sections 7 and 8 by a movable piston shaft 9 and located in the rotor 3. The outer section 7 has an outer channel 14 and an outer slot 13 arranged in the housing 1 and extending along the length of the outer section 7.
EFFECT: improvement of performance with decrease of air-hydraulic and mechanical losses and increase of efficiency of the device.
