ABSTRACT:
A variable capacity type slant plate compressor including a crank chamber a suction chamber and a discharge chamber is disclosed. The crank chamber is linked by a first communication path to the suction chamber, and is linked by a second communication path to the discharge chamber. A first valve control mechanism is disposed within the first communication path. A second valve control mechanism is disposed within the second communication path. The first valve control mechanism controls the opening and closing of the first communication path so that the suction chamber pressure is maintained at a predetermined constant value. The second communication path is compulsorily opened by operation of the second valve control mechanism in response to an external signal so as to compulsorily minimize the capacity of the compressor. A throttling device is disposed within the second communication path between the discharge chamber and the second valve control mechanism so that the capacity of the compressor is compulsorily quickly minimized without damage of the internal component parts of the compressor.
