TURBOCOMPRESSOR Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to design of turbocompressors intended for supercharging automobile and tractor diesel engines. Proposed turbocompressor contains rotor with compressor and turbine wheels mounted on rotor brackets and bearing bushing installed in stator and fixed from turning and provided with support belts for rotor. Ring grooves connected by oil channel are made on outer diameter of bearing bushing. Holes are made in ring grooves to feed oil to support belts. Radial hole made between support belts from turbine side communicates with oil channel, being displaced from axis to side of rotor rotation, and oil drain hole is provided. Conductive temperature-sensitive resistor and heat screen are installed between turbine housing and stator. EFFECT: improved reliability and performance characteristics of turbocompressor, increased service life, reduced negative influence of temperature on engine lubrication system. 4 dwg
