Abstract
A compressor for a refrigeration circuit of a domestic refrigerator includes a piston being moveable within a compression chamber of a cylinder for compressing a refrigerant. The piston is contactlessly mounted in radial direction relative to the cylinder by a gas pressure bearing formed from the refrigerant. An inlet valve regulates a volume flow of uncompressed refrigerant from a low-pressure inlet of the compressor into the compression chamber and an outlet valve regulates a volume flow of compressed refrigerant from the compression chamber to a high-pressure outlet of the compressor. A stop valve between the low-pressure inlet and the high-pressure outlet prevents a backflow of refrigerant from the high-pressure outlet to the low-pressure inlet when the compressor is deactivated. A domestic refrigerator including a compressor and a method for operating a compressor for a refrigeration circuit of a domestic refrigerator are also provided.
