ROTARY VANE MACHINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; pumps, compressors, hydraulic motors, pneumatic motors, gas expansion machines. SUBSTANCE: machine has housing with covers accommodating distributing plates with channels to let working medium in and out. Stator on rolling-contact bearing installed for rotation relative to housing and eccentrically installed rotor (with eccentricity relative to stator) are found inside housing. Vanes fitted in radial slots or rotor. Rings installed for movement in radial directions are mounted on end face surfaces of rotor in its ring slots. Outer diameter of each ring is calculated by formula: d= D-2h, where D is inner diameter of stator, h is height of vane. EFFECT: simplified design of machine and increased reliability. 2 dwg
