1. A capacity control valve comprising:
a discharge-side passage for providing communication between a discharge chamber for discharging a fluid, and a control chamber for controlling the discharge rate of the fluid; a first valve chamber formed in the middle of said discharge-side passage; a suction-side passage for providing communication between a suction chamber for drawing in the fluid and said control chamber; a suction port formed in the middle of said suction-side passage; a first valving element for opening and closing said discharge-side passage in said first valve chamber; a second valve chamber formed between said control chamber and said first valve chamber in the middle of said suction-side passage; a pressure-sensitive body disposed in said second valve chamber, said pressure-sensitive body exerting an urging force in a direction for opening said first valving element by elongation, and undergoing constriction in accordance with an increase in the surrounding pressure; an adapter provided to a free end of said pressure-sensitive body in the elongation and constriction direction, said adapter having an annular bearing surface; a second valving element linked to said first valving element and provided with an annular engaging surface for opening and closing said suction-side passage by engagement with, and disengagement from, the bearing surface of said adapter in said second valve chamber; and a solenoid for exerting an electromagnetic driving force on said first valving element; wherein a bellows-type valve that uses a bellows is adopted in said first valving element, and a fixing bracket joined in an airtight manner to the other end of the bellows; and wherein the fixing bracket is fixed in an airtight manner to a valve body between said first valve chamber and said suction port.
