摘要： A damping valve includes a valve seat member provided with a port, a valve body that opens or closes the port, a tubular spool that abuts on a side of the valve body opposite to the valve seat member, a spool holding member that has an outer circumference where the spool is mounted movably along an axial direction, a ring mounted to the outer circumference of the spool holding member, the ring contacting slidably with an inner circumference of the spool, and a back-pressure chamber partitioned by the spool and the spool holding member, the back-pressure chamber being configured to bias the spool such that the valve body is pressed toward the valve seat member using an internal pressure, wherein the internal pressure of the back-pressure chamber is applied to an inner circumferential side of the ring.

摘要： To provide a solenoid, a solenoid valve, and a damper in which when the amount of current supplied to the solenoid is small, the thrust of the solenoid to bias an object in one direction can be made small, and at the same time, even when the solenoid is not energized, the object can be biased in the same direction as that of the thrust. The solenoid (S) includes a coil (40), a first movable iron core (45) and a second movable iron core (46) that are attracted in a direction away from each other by energizing the coil (40), a coil spring (47) that biases the first movable iron core (45) toward the second movable iron core (46), and a leaf spring (48) that restricts the approach of the first movable iron core (45) and the second movable iron core (46).
