ROTARY PUMP-COMPRESSOR Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: proposed pump-compressor contains rotor coaxial with stator and made in form of two disks resting on two supports and secured by pressure wing in form of larger part of ring whose axis of solid of revolution is displaced relative to axis of rotation of rotor through eccentricity. Round cylindrical stator is installed inside wing along axis of rotation of rotor. Generating line of its cylindrical part at place of meeting passes at minimum distance from generating line of inner surface of pressure wing. Slots are made in body of stator in which two plate partitions are installed, being fastened by spring-loaded rods. Partitions thrust against inner surface of wing and supporting strips. Drive shaft is installed on one end of axle of rotation of rotor. Second end of rotor is installed on outlet branch pipe. Pump-compressor is secured on support by said branch pipe. With rotor rotating, wind rotates around cylindrical part of stator and encloses medium by pressure plane. Then pressure plane of wing comes in contact with partitions forcing it into slot, compresses medium and delivers compressed medium under values.

EFFECT: effective filling up of compression chambers, high compression ratio.
