Embodiment Construction

[0010] The figures show a housing part 1 which can, for example, be an integral component of the compressor housing. Embedded in the housing part 1 is a diaphragm fuse 3 which is acted on its side 7 of the high pressure 5 which builds up in the discharge region of the compressor. On the side 9 of the diaphragm fuse, that is to say in the region 11 of the safety device, the diaphragm fuse is acted upon in the undestructed state with atmospheric pressure 15 because the overflow valve 13 is not closed leak-tight and Atmospheric pressure 15 can thus be established in region 11 . As described in this embodiment, the overflow valve 13 can for example consist of a spherical valve body 17 and a conical valve seat 19, wherein the spherical valve body 17 is pressed against the valve by a spring 21. Inside the valve seat 19. The opening pressure of the overflow valve is determined by the preload force of the spring 21 , which can be adjusted via a corresponding abutment 23 of the sprin...

Abstract

The invention relates to a compressor, particularly for air conditioners in motor vehicles, comprising a safety device for limiting high pressure, whereby the safety device is hermetically sealed until first responding, after which it slowly reduces the system pressure.

Description

technical field [0001] The invention relates to a compressor with a safety device for high-pressure limitation, in particular a compressor for an air-conditioning system in a motor vehicle. Background technique [0002] Such compressors are known. There are compressors which unload the entire refrigerant-oil mixture to the environment via diaphragm fuses which rupture when the maximum pressure is exceeded. The disadvantage of these compressors is that, for example, a motor vehicle with an uncoupled compressor cannot move after the diaphragm fuse has activated without risking damage to the compressor. [0003] Furthermore, some compressors with relief valves for the refrigerant R134A are disclosed. But their structural form cannot be directly transferred to use the refrigerant CO in their new state without risking significant leakage rates 2 air conditioning equipment. In addition, the currently used overflow valve for refrigerant R134A also has a problem that sealing per...
