摘要： An expansion valve having a high valve opening adjustment accuracy includes: a valve housing which is provided with an inlet port allowing a refrigerant from a condenser to pass therethrough and an outlet port allowing a refrigerant toward an evaporator to pass therethrough; a valve body which is driven by a solenoid; a valve seat on which the valve body sits; and an urging member configured to urge the valve body in a valve closing direction, a space is formed on a valve opening direction side of the valve body, and the refrigerant on the valve closing direction side in relation to the valve body flows into the space.

摘要： Provided is a capacity control valve that can be produced with good workability and at a low cost. A capacity control valve includes: a valve housing in which a flow passage is formed; and a valve body disposed inside the valve housing and driven by a solenoid. A valve seat member having a tubular shape and including a valve seat on which the valve body is seatable is press-fitted into the valve housing, and at least the valve seat of the valve seat member is harder than the valve housing.

摘要： Disclosed is a valve in which a small driving force of a drive source is required when the valve is closed. A valve includes a valve housing and a valve body to be driven by a drive source, and controls a flow rate of a fluid flowing through a through-flow passage in a direction opposite a closing direction of the valve body, by moving the valve body from a control region to a closing region. The valve body has an effective pressure-receiving area where a pressure of the fluid acts on the valve body. The effective pressure-receiving area is switched between the effective pressure-receiving area in the control region and the effective pressure-receiving area in the closing region. The effective pressure-receiving area is smaller than the effective pressure-receiving area Rs1.

摘要： A capacity control valve includes a valve housing to which a suction fluid having a suction pressure and a control fluid having a control pressure are supplied; a solenoid; a CS valve body that partitions an inside of the valve housing into a first space, and a second space and moves according to the suction pressure of the suction fluid and the control pressure of the control fluid, and a CS valve seat with which the CS valve body is configured to come into contact; a biasing member biasing the CS valve body in a valve opening direction of the valve; and a pilot valve formed of a pilot valve body to be driven by the solenoid and a pilot valve seat with which the pilot valve body is configured to come into contact.
