Abstract:
A capacity control valve includes: a pressure-sensitive body positioned in a third valve chamber; an adapter provided on the free end of the pressure sensitive body having a circular seating surface; a third valve part that moves integrally with a valve element in the third valve chamber and has a circular engagement surface that opens/closes intake-side passages by engaging with and separating from the seating surface of the adapter; and a solenoid that applies an electromagnetic drive force to the valve element in the direction of closing a first valve part, wherein the pressure-sensitive body is formed by a formed bellows made of material having greater yield stress than phosphor bronze, and the formed bellows has its diameter set smaller and its stroke longer than the diameter and stroke of a phosphor bronze bellows.

Claim (Index 1):
A capacity control valve, comprising:\n discharge-side passages communicating a discharge chamber that discharges fluid and a control chamber that controls a discharge rate of fluid; a first valve chamber formed along the discharge-side passages; intake-side passages communicating an intake chamber that takes in fluid and the control chamber; a second valve chamber formed along the intake-side passages; a valve element that integrally has a first valve part that opens/closes the discharge-side passages in the first valve chamber and a second valve part that opens/closes the intake-side passages in the second valve chamber, where the first and second valve parts open/close in opposite directions due to reciprocating motion; a valve body accommodating the valve element in a manner allowing a reciprocating motion, and cooperating with the valve element to form the first valve chamber and the second valve chamber; a third valve chamber formed along the intake-side passages at a position closer to the control chamber than to the second valve chamber; a pressure-sensitive body positioned in the third valve chamber to apply, by extending, a bias force in a direction of opening the first valve part, and also to contract as a surrounding pressure increases; an adapter provided on a free end of the pressure-sensitive body in extending/contracting direction and having a circular seating surface; a third valve part that moves integrally with the valve element in the third valve chamber and has a circular engagement surface that opens/closes the intake-side passages by engaging with and separating from the seating surface of the adapter; and a solenoid that applies an electromagnetic drive force to the valve element in a direction of closing the first valve part; the capacity control valve characterized in that: the valve element is located between the first valve chamber and the second valve chamber, and has an outer circumferential face part slidably movable relative to an inner circumferential face of the valve body; plural of screw grooves are formed on the outer circumferential face part; each of the plural threads of screw grooves communicates with the first valve chamber and does not communicate with the second valve chamber, when the first valve part is closed, and communicates neither with the first valve chamber nor the second valve chamber, when the first valve part is opened.
