ROTARY MACHINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering; compressors, pumps and internal combustion engines. SUBSTANCE: proposed rotary machine has hollow cylindrical housing with end shields accommodating two coaxially installed blades on surface of which spring-loaded axial and radial sealing members are installed. End face surface of blades are sealed by radial and six segment plates whose ends are connected by cylindrical dowels with cuts and are installed in slots over circle. Cylindrical surfaces of lower part of blade cantilevers are sealed by radial and axial plates fitted in L-shaped cuts of segment seals in contact with cylindrical surface of coaxial blade and end shield. EFFECT: increased efficiency and improved reliability of machine. 3 dwg
