Capacity control valve

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.

A capacity control valve capable of being downsized with the small number of parts is provided. A capacity control valve includes a valve housing provided with a suction port through which a suction fluid of suction pressure Ps passes, and a control port through which a control fluid of control pressure Pc passes, a valve element configured to be driven by a solenoid, a spring that biases the valve element in a direction opposite to a driving direction of the solenoid, and a CS valve formed by a CS valve seatand the valve element and configured to open and close a communication between the control port and the suction port in accordance with a movement of the valve element. The control pressure Pc is controlled by opening and closing the CS valve.

A valve includes a valve housing provided with an inlet port and an outlet port; a valve body configured to be driven by a drive source; a spring that urges the valve body in a direction opposite a direction of driving by the drive source. A valve seat is formed at an edge of a through-flow passage. The valve body and the valve seat forms a poppet valve that controls a flow rate in accordance with a movement of the valve body. A flow passage on a downstream side of the poppet valve is provided with a reduction region where a flow passage cross-sectional area tends to decrease toward a downstream side.

A valve includes: a housing having a primary pressure space and a secondary pressure space; a valve seat disposed between the primary pressure space and the secondary pressure space; a valve body that is driven in an axial direction by a driving source to be seated on or separate from the valve seat; and a communication passage that provides communication between a back space adjacent to one of the primary pressure space and the secondary pressure space and remaining one of the primary pressure space and the secondary pressure space. A partition member is disposed between the valve housing and the valve body, and the back space and the one of the primary pressure space and the secondary pressure space are partioned off from each other in a sealed state by the partition member.

To provide a valve capable of suppressing contamination from being caught between a fixed iron core and a rod. The valve includes: a valve housing; a valve body; a valve seat having the valve body seated thereon; a drive source for driving the valve body by a rod; and an urging member for urging the valve body in a direction opposite to a driving direction of the drive source. One of the valve body and the rod includes a guide concave portion which guides remaining one of the valve body and the rod in a relative fitting direction.

A capacity control valve includes a valve housing provided with a suction port through which a suction fluid of suction pressure Ps passes, and a control port through which a control fluid of control pressure Pc passes, a valve element configured to be driven by a solenoid, a spring that biases the valve element in a direction opposite to a driving direction of the solenoid, and a CS valve formed by a CS valve seat and the valve element, the CS valve being configured for opening and closing a communication between the control port and the suction port in accordance with a movement of the valve element. The capacity control valve further includes communication controller that controls a communication between the control port and a space on a back surface side of the valve element.

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.

Flow rate control valve

A capacity control valve includes a valve housing provided with a suction port through which a suction fluid of suction pressure passes, and a control port through which a control fluid of control pressure passes, a valve element configured to be driven by a solenoid, a spring that biases the valve element in the direction opposite to the driving direction by the solenoid, and a CS valve formed by a CS valve seat and the valve element and configured for opening and closing a communication between the control port and the suction port by movement of the valve element.
