FIELD: machine engineering.
SUBSTANCE: rotary-vane machine comprises a stationary housing 1 with an axis 4 connected to an eccentrically located second axis 6, a supply duct 10 and a discharge duct 11 of working medium. Around the axis 6, the vanes 5 are movably arranged. Inside the vanes 5 there is a working chamber 2 divided into two working sections by a piston 9 with a movable piston shaft 8. The shaft 8 is attached to the rotor 3 rotated about the axis 4. The duct 10 passes through the shaft 8. The duct 11 is made in the housing 1 and extends along the working section, providing an increase in the ejection velocity of the working medium.
EFFECT: improved operational characteristics with reduction of pneumo-hydraulic and mechanical losses and increased efficiency of the device.
