Abstract

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.
