の付勢力との合力により一部稼動位置側に付勢さ
れ、該合力と高圧室内の制御圧との差により全稼
動位置と一部稼動位置との間で回動して圧縮開始
時期を制御する制御部材を備え、前記ねじりコイ
ルばねが吸入室内に設けられた可変容量型圧縮機
において、所定温度以下で伸張した形状をとつて
前記制御部材を一部稼動位置側に付勢し、所定温
度以上で収縮した形状をとつて前記制御部材を全
稼動位置に回動させる形状記憶合金製のねじりコ
イルばねを、前記ねじりコイルばねに代えて又は
該ねじりコイルばねに付加して前記吸入室内に設
けたことを特徴とする可変容量型圧縮機。 The resultant force of the low pressure introduced into the low pressure chamber and the biasing force of the torsion coil spring partially biases the operating position, and the difference between the resultant force and the control pressure within the high pressure chamber causes the full operating position and the partially operating position to be moved. In a variable capacity compressor, the torsion coil spring is provided in a suction chamber, and the control member is rotated between 1 and 2 to control the compression start timing. Instead of the torsion coil spring, a torsion coil spring made of a shape memory alloy that biases the control member toward the fully operating position, assumes a contracted shape at a predetermined temperature or higher, and rotates the control member to the fully operating position, or A variable displacement compressor, characterized in that the compressor is provided in the suction chamber in addition to a coil spring.
