COMPRESSOR, SYSTEM CONTAINING COMPRESSOR AND METHOD INCLUDING USE OF FLUID CIRCULATION SYSTEM INCLUDING COMPRESSOR Russian patent published in 2015 - IPC F04C29/00 F04C18/02 F04C27/00 

FIELD: machine building.

SUBSTANCE: invention relates to the compressor, in particular to sealing assembly of the compressor. The compressor has housing, first and second spiral elements and sealing assembly. The casing limits the first and second pressure areas. The first spiral element has first end plate limiting the chamber. The sealing element encloses the discharge channel and tightly for fluid isolates the first and second pressure areas from each other. The sealing element has the first and second sealing elements. The first sealing element excludes connection between the chamber and the second pressure area, when the first fluid pressure in the second pressure area exceeds the second fluid pressure in chamber. The first sealing element creates a leak path when the first fluid pressure is lower then the second fluid pressure. The second sealing element tightly for fluid isolates the chamber and the second pressure area when the first fluid pressure is lower then the second fluid pressure.

EFFECT: invention ensures effective and reliable operation of the compressor.
