A capacity control valve comprising: a discharge-side channel (31, 32) for interconnecting a discharge chamber for discharging a fluid and a control chamber for controlling the amount of the fluid discharged; a first valve chamber formed partway along said discharge-side channel (31, 32); an intake-side channel for interconnecting an intake chamber for drawing in the fluid and said control chamber; a second valve chamber formed partway along said intake-side channel; a valve body integrally comprising a first valve part for opening/closing said discharge-side channel (31, 32) in said first valve chamber and a second valve part for opening/closing said intake-side channel (31, 32) in said second valve chamber, a reciprocating motion performed by the valve body causing mutually opposite opening/closing actions to be performed; a third valve chamber formed partway along said intake-side channel, nearer said control chamber than said second valve chamber; a pressure-sensitive body arranged in said third valve chamber, the pressure-sensitive body extending and thereby exerting an urging force in a direction so as to open said first valve part, and contracting in concert with an increase in ambient pressure; an adaptor provided to a free end, in the direction of extension, of said pressure-sensitive body, the adaptor having an annular seat surface; a third valve part having a tapered engaging surface, which moves integrally with said valve body in said third valve chamber and engages/disengages with respect to the seat surface of the adaptor, thereby opening/closing said intake-side channel; and a solenoid for exerting an electromagnetic driving force on said valve body in a direction so as to close said first valve part, in response to a pulse width modulation signal having a uniform frequency; a discharged-fluid-receiving part of larger diameter than the diameter of a valve hole interconnecting the first valve chamber and the third valve chamber, the discharged-fluid-receiving part being provided to an outer periphery section of said third valve part, characterized in that said discharged-fluid-receiving part is formed by providing a flange to the outer periphery section of said third valve part. a discharge-side channel (31, 32) for interconnecting a discharge chamber for discharging a fluid and a control chamber for controlling the amount of the fluid discharged; a first valve chamber formed partway along said discharge-side channel (31, 32); an intake-side channel for interconnecting an intake chamber for drawing in the fluid and said control chamber; a second valve chamber formed partway along said intake-side channel; a valve body integrally comprising a first valve part for opening/closing said discharge-side channel (31, 32) in said first valve chamber and a second valve part for opening/closing said intake-side channel (31, 32) in said second valve chamber, a reciprocating motion performed by the valve body causing mutually opposite opening/closing actions to be performed; a third valve chamber formed partway along said intake-side channel, nearer said control chamber than said second valve chamber; a pressure-sensitive body arranged in said third valve chamber, the pressure-sensitive body extending and thereby exerting an urging force in a direction so as to open said first valve part, and contracting in concert with an increase in ambient pressure; an adaptor provided to a free end, in the direction of extension, of said pressure-sensitive body, the adaptor having an annular seat surface; a third valve part having a tapered engaging surface, which moves integrally with said valve body in said third valve chamber and engages/disengages with respect to the seat surface of the adaptor, thereby opening/closing said intake-side channel; and a solenoid for exerting an electromagnetic driving force on said valve body in a direction so as to close said first valve part, in response to a pulse width modulation signal having a uniform frequency; a discharged-fluid-receiving part of larger diameter than the diameter of a valve hole interconnecting the first valve chamber and the third valve chamber, the discharged-fluid-receiving part being provided to an outer periphery section of said third valve part, characterized in that said discharged-fluid-receiving part is formed by providing a flange to the outer periphery section of said third valve part.
