The swash plate compressor for a co2 - air-conditioning system with a thickness of 5 to 20 μm between reciprocating piston and the compression cylinder

摘要

The swash plate compressor for a co₂-Air conditioning system, having a compressor housing, in which a drive shaft with a wobble plate is arranged, the at least a reciprocating piston arranged in a compression cylinder for sucking in and compacting of the co₂-Drives refrigerant, and with a suction valve and an outlet valve in the compression chamber of the compression cylinder, characterized in that between the reciprocating piston (6) and the compression cylinder (5), an annular gap (rs) with a width of substantially 5 to 20 μm in the radial direction is formed in which the co₂-Refrigerant acts as a sealing medium, and in that the materials for the reciprocating piston (6) and the compression cylinder (5) the same or substantially the same thermal expansion coefficients have.
