Abstract
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.
