TURBINE EXPANSION ENGINE (VERSIONS) Russian patent published in 2003 - IPC

FIELD: constructions of turbine expansion engines. SUBSTANCE: turbine expansion engine includes housing with cavities; shaft mounted in housing on bearing assemblies; compressor and turbine mounted on shaft. System for controlled gas discharge includes tube arranged in housing. Said tube is connected by its one end through duct of housing with cavity arranged between compressor and turbine and by its other end through control device it is connected with outlet cavity of turbine. In first variant turbine expansion engine includes slit sealings. Axial motion pickup is placed in housing with possibility of connecting its outlet with outer apparatus. At least two end sealings are arranged in addition in housing. In second variant each bearing assembly of turbine expansion engine is electromagnetic one. At least two pickups for detecting axial motion of shaft and at least two pickups for detecting radial motion of shaft are arranged in housing with possibility of connecting outlet of each pickup to outer apparatus. EFFECT: enhanced operational and thermotechnical characteristics of turbine expansion engine. 9 cl, 5 dwg
