摘要： A damping valve includes: a disk with a port and a valve seat surrounding the port; a leaf valve that opens and closes the port by causing the front side to sit on and leave the valve seat; a tubular housing provided on the back side of the leaf valve; an annular spool that abuts on the back of the leaf valve and is slidably inserted into the inner circumference of the housing to form a back pressure chamber that causes back pressure to act on the leaf valve inwardly together with the housing; an annular spring support portion that is located on the back side of the leaf valve, faces the inside of the back pressure chamber, and has a smaller outer diameter than an inner diameter of the spool; and an annular leaf spring that is interposed between one end of the spool that is an opposite side end of the leaf valve and the spring support portion and presses the spool in a direction of abutting on the leaf valve.

摘要： A damping valve includes a valve element member, a disc spring, and a solenoid. The valve element member opens and closes an upstream side and a downstream side of a pilot passage by a pressure control valve element seated on and liftable from a pressure control valve seat and an open/close valve element seated on and liftable from an open/close valve seat. The disc spring is interposed between a stepped part and the valve element member. The disc spring biases the valve element member in a direction in which the pressure control valve element separates from the pressure control valve seat and in which the open/close valve element approaches the open/close valve seat. The solenoid is configured to drive the valve element member against a biasing force by the disc spring. In a state in which the disc spring has a natural length, a clearance is formed between the open/close valve element and the open/close valve seat.

摘要： A damping valve includes a main valve opening and closing a main passage, and a pilot passage reducing a pressure of the upstream of the main passage by a throttle to guide as a back-pressure biasing the main valve to the closing direction. A pressure control valve being disposed on the downstream of the throttle and including a seating portion controlling the back-pressure, and a switching valve including a circular depressed portion opening and closing the pilot passage are integrated and controlled by a single solenoid. The damping valve includes fail passages being branched from the downstream of the throttle to bypass the main valve, and a fail valve opening and closing the fail passage. The switching valve is arranged on the upstream of the pressure control valve in the pilot passage. The fail passages are branched from the upstream of the switching valve of the pilot passage.
