FIELD: engines and pumps.
SUBSTANCE: proposed system comprises radial, face and tangential seals. Radial seals are fitted in grooves of rotor vanes. Tangential seals represent rectangular plates fitted in rotor groove walls on both sides of the vanes. Radial seals represent "П"-like plates spring-loaded towards housing work surface. Each of said plates is coupled with counterweight by bell cranks fitted in pairs relative to feet of "П"-like plates. End of bell cranks share common axles fitted in blocks arranged in counterweight openings and feet of "П"-like plates. Aligned axles of bell cranks are fitted in vanes walls. Face seals represent plates fitted on both sides of the rotor, parallel to its rotational axis, and are furnished with adjustable thrusts.
EFFECT: efficient sealing.
