SEALED ROTARY COMPRESSOR AND COOLING CIRCUIT DEVICE Russian patent published in 2008 - IPC F04C18/356 F04C23/00 

FIELD: mechanical engineering; compressors.

SUBSTANCE: invention relates to sealed rotary compressor included into cooling circuit, for instance, of air conditioner and to cooling circuit device with said rotary sealed compressor included into cooling circuit. High pressure in maintained inside housing of sealed rotary compressor. Compressor has first cylinder 8A and second cylinder 8B with cylinder chambers 14a, 16b, accordingly, which accommodate rollers 13a, 13b. Moreover, compressor is provided with plates 15a, 15b dividing cylinder chambers and chambers of plates 22a, 22b which accommodate rear end parts of plates. Plate in first cylinder is pressed on and shifted by spring 26 found in plate chamber. Plate in second cylinder is pressed on and displaced depending on pressure difference between pressure inside housing in plate chamber and suction or discharge pressure in cylinder chamber.

EFFECT: simplified design of pressing and shifting structures for plates of one of cylinders, improved reliability.
