Claim:
1. A compressor for use in air conditioning systems of a motor vehicle, the compressor comprising: a housing including a first housing part and a second housing part which together define a pressure chamber, said first housing part having a first sealing surface and said second housing part having a second sealing surface, said first and second housing parts being connected by a plurality of connecting elements applying a contact pressure on said first and second sealing surfaces; a first groove formed in said first sealing surface of said first housing part and extending in a circumferential direction; a first vent opening including a radially-extending first relief channel formed in said first housing part and extending from said first groove to the environment of the compressor, wherein said first groove and first vent opening are configured such that a pressurized medium is collected in said first groove and at least partially discharged from said first groove to the environment via said first vent opening in response to the pressurized medium within said pressure chamber exceeding a predetermined maximum pressure; a second groove formed in said second sealing surface of said second housing part and extending in a circumferential direction; and a second vent opening including a radially-extending second relief channel formed in said second housing part and extending from said second groove to the environment of the compressor, wherein said second groove and said second vent opening are configured to cooperate with said first groove and said first vent opening to allow pressurized medium collected in at least one of said first and second grooves to be discharged to the environment from at least one of said first and second vent openings in response to the pressurized medium within said pressure chamber exceeding said predetermined maximum pressure.
