Beschreibung
Zusammenfassung:	FIELD: transport engineering. ^ SUBSTANCE: invention relates to low-capacity turbocompressors-gas-expansion machines for transfer of hot contaminated gas-air mixture and for cooling air in vehicle air conditioning and air cooling system. proposed turbocompressor-gas-expansion machine has housing accommodating shaft installed inside housing on antifriction bearings with fitted on wheels of compressor and turbine-gas-expansion machine secured on ends of shaft. Bearings are grease packed. Bearing unit from side of compressor is installed with clearance relative to housing. clearance is divided by partition made of heat-insulating material into two spaces. Space from side of bearing unit communicates with atmosphere and with outlet of turbine-gas-expansion machine for cooling bearing by part of cooled air flow. Space from side of compressor is sealed to play part of heat shield. ^ EFFECT: simplified design, reduced overall dimensions of turbocompressor-gas-expansion machine, provision of normal temperature conditions for operation of bearing. ^ 3 cl, 1 dwg
