摘要： A capacity control valve for a variable-capacity compressor such as used in an air-conditioning system in a motor vehicle is provided, wherein foreign matter is prevented from being caught in the sliding parts and leakage on the sliding parts is prevented from occurring by configuring the capacity control valve so that there are no sliding parts between the valving element and the housing (valve body). The valve includes a bellows-type valve that includes a bellows and a fixing bracket joined in an airtight manner to an end of the bellows. The fixing bracket is fixed in an airtight manner to a valve body between a first valve chamber and a suction port.
