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.
Claims16
1-13. (canceled)
A compressor, comprising:
- a safety device for limiting high pressure, wherein the safety device is hermetically sealed until a first response, and wherein the safety device allows a slow release of system pressure after the first response.
A safety device for a compressor in an air-conditioning system of a motor vehicle, the safety device comprising:
- a rupture disk in contact with a refrigerant of the air-conditioning system and configured to rupture when a pressure of the refrigerant exceeds a first predetermined pressure;
- and
- a pressure valve disposed in a closed position downstream of the rupture disk, and configured to open at a second predetermined pressure lower than the first predetermined pressure so as to release refrigerant in the event of a rupture of the rupture disk, a predetermined leak being associated with the pressure valve in the closed position so as to allow atmospheric pressure to contact a downstream side of the rupture disk when the rupture disk is intact and to allow a slow leak of the refrigerant when the rupture disk is ruptured and when the pressure of the refrigerant is below the second predetermined pressure.
