Compressor comprising a pressure-relief groove

摘要

A compressor is disclosed. In one aspect, the compressor includes a pressure chamber which is delimited by at least two housing parts, the housing parts including sealing surfaces that are connected by a connection device which applies a contact pressing force between the sealing surfaces. At least one groove extending in a circumferential direction is arranged on at least one sealing surface. At least one relief opening is arranged on at least one of the housing parts. The relief opening connects the groove to the surroundings of the compressor and emanates from the groove. The groove is arranged such that when a predetermined maximum pressure is exceeded in the pressure chamber, a pressure-building medium can gather in the groove and at least partially escape through the relief opening.

主权项

1. A compressor with a pressure chamber, which is delimited by at least two housing parts for use in an air conditioning system of a motor vehicle, wherein the housing parts comprise a plurality of sealing surfaces, which are connected by a connecting device applying a contact pressure on the sealing surfaces,
at least one groove arranged on at least one of the sealing surfaces and extending in a circumferential direction, at least one vent opening arranged on at least one of the housing parts and extending from the groove to connect the groove with the environment of the compressor, and wherein the groove is arranged in such a way that on exceeding a predefined pressure in the pressure chamber a pressurization medium is collected in the groove and at least partially discharged via the vent opening, wherein the plurality of sealing surfaces includes a first sealing surface and a second sealing surface, and wherein the at least one groove includes a first groove arranged on the first sealing surface and a second groove arranged on the second sealing surface.
