Safety device for air conditioning compressor has safety units for high pressure, drive chamber pressure, and suction pressure zones all in functional connection with each other

摘要

The compressor has a swash plate/wobble plate, with tilt varied by the pressure differential between the high pressure in the discharge pressure zone (31) and the driving chamber pressure (33). The safety device has a valve device (35), a pressure limitation valve (36), and an additional pressure limitation valve (30) or burst plate. The safety units for the high pressure zone, driving chamber pressure zone, and suction pressure zone, are functionally coupled to each other.
