Disclosed is a solenoid valve for controlling a flow rate of a flow path connecting a first port to a second port, the solenoid valve including: a valve housing installed in a modulator block; an armature disposed inside the valve housing and reciprocating in an axial direction thereof to adjust a flow rate of a working fluid; and a first elastic member having a damper part, which is inserted between the magnet core and the armature, and providing the armature with an elastic force in a direction opposed to a driving force of the magnet core.

An assembly includes an inlet tube. The assembly includes a first outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube. The solenoid assembly has a spring urging the plunger to the closed position. The solenoid assembly has a strain gage fixed to the spring. A strain detected by the strain gage indicates whether the plunger is at the closed position.

A solenoid valve having a solenoid body with a solenoid receiving cavity and a flow receiving passage. A solenoid assembly is provided in the solenoid receiving cavity. A valve is provided in the flow receiving passage. An armature extends from the solenoid to the valve. The solenoid valve also includes a control circuitry, a power connection and a bidirectional communications connection. At least one sensor is provided in the flow receiving passage. The at least one sensor is in communication with the control circuitry. When in operation, power is continuously supplied through the power connection and the actuation of the solenoid valve is initiated by the bidirectional communications connection.

A flow control valve includes a bobbin around which a solenoid coil is wound, a plunger inserted into the bobbin so as to be capable of sliding, a core in which is provided an outflow port from which a fluid flows, a spring that biases the plunger in a direction away from the core, and a valve body incorporated into the plunger so as to be disposed facing the outflow port. During a non-operating state, the valve body is disposed at a first position distanced from the outflow port. During an operating state, the plunger is pulled toward the core against a biasing force of the spring, and is not in contact with the core when the valve body is at a second position in which the valve body blocks the outflow port.

A solenoid valve assembly with a manual override is provided that includes a solenoid valve housing that is supportive of a valve seat, a plunger-type armature valve element fluidly communicative with a fluid source and initially pressure balanced to remain in a closed position relative to the valve seat and an electromagnet configured to generate a magnetic flux to move the plunger-type armature-valve element into an open position relative to the valve seat. The solenoid valve assembly with a manual override also includes a manual actuation assembly configured to generate an applied force to move the plunger-type armature valve element into the open position relative to the valve seat.

A valve armature of a solenoid valve includes an armature body having a blind hole in which an elastomer seal is vulcanized in. The armature body is manufactured in a cold forming process, in which a final axial linear dimension of the armature body is also determined. Furthermore, a valve having such a valve armature is presented.

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 seat 10a and 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.
