Compressor for compressing gas for refrigerant circuit of household refrigerator, has outer casing wall that forms tribological system during operation of compressor with inner casing wall of working chamber
The compressor (5) has a working chamber provided with an inner casing wall, an inlet and an outlet. A piston, particularly reciprocating piston, is axially adjusted for changing the volume of the working chamber. An outer casing wall forms a tribological system during the operation of the compressor with the inner casing wall of the working chamber. The outer casing wall of the reciprocating piston has a structure, which is formed to prevent demolishing of a lubricant film between the inner casing wall of the working chamber and the outer casing wall of the reciprocating piston. An independent claim is included for a household refrigerator, which has an inner space.
