ROLLER-VANE COMPRESSOR Russian patent published in 2007 - IPC F01C1/00 

FIELD: mechanical engineering; roller-vane compressors.

SUBSTANCE: proposed roller-vane compressor has hollow housing with two working medium inlet channels, one of which communicates with working medium source, and two working medium outlet channels, one of which communicates with consumer and the other communicates through main line with second inlet channel. Compressor housing has relief slots to provide hydraulic connection with outlet channel communicating with consumer through slot of roller-separator and with cavities for rollers-separators with slots and relief space made on its inner surface. Relief space communicates hydraulically with second inlet channel. Rotor with vanes is arranged in housing space, and in cross section, distance "l" between nearest mating points on inner surface of housing with wall of relief space and cavities for roller-separator is less than distance L between nearest mating points on inner surface of housing and wall of inlet channel communicating with consumer and with wall of outlet channel communicating by main line with second inlet channel. Heat exchanger can be arranged in main line.

EFFECT: increased efficiency of roller-vane compressor.
