摘要

A variable capacity type slant plate compressor including a crank chamber, a suction chamber 241 and a discharge chamber 251 is disclosed. The slant plate is disposed in the crank chamber at a variable slant angle. The slant angle varies in dependence on the crank chamber pressure. The crank chamber is linked by a first communication path (400a) to the suction chamber, and is linked by a second communication path (500a) to the discharge chamber. A first valve control mechanism (400) is disposed within the first communication path. A second valve control mechanism (500) is disposed within the second communication path. The slant angle may be varied by operation of the first valve control mechanism which controls an open and close of the first communication path so that the suction chamber pressure is adjusted at a predetermined constant value. The second communication path is compulsorily opened by operation of the second valve control mechanism so as to compulsorily minimize the capacity of the compressor when the energy consumed in operation of the compressor is demanded to be reduced. A throttling device (249a) 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.
