Abstract: A damping force-adjusting valve includes: a valve disc that includes an annular inner peripheral seat portion on which a leaf valve is stacked, an annular valve seat where the leaf valve is separated/seated, and an annular window provided between the inner peripheral seat portion and the valve seat; and a sustaining portion that is provided between the inner peripheral seat portion and the valve seat and suppresses deformation of the leaf valve. An end of the sustaining portion facing the leaf valve more protrudes toward the leaf valve than an end of the valve seat facing the leaf valve when seen in an axial direction.

Abstract: A damping valve includes a valve disc, a ring-shaped leaf valve, and a biasing mechanism. The valve disc includes a passage and a valve seat. The valve seat surrounds an exit end of the passage. The leaf valve is stacked on the valve disc. The leaf valve separates from and is seated on the valve seat to open and close the passage. The biasing mechanism causes a variable biasing force to act on the leaf valve to the valve disc side. The entire leaf valve is configured to axially retreat with respect to the valve disc. A clearance is formed between the leaf valve and the valve seat in a state in which the leaf valve is stacked on the valve disc with no load.

Abstract: A damping valve includes: an electromagnetic valve having: a pressure control valve that controls a pressure of an upstream side of the pressure control passage; a shut-off valve integrated into the pressure control valve and provided in an upstream side of the pressure control valve of the pressure control passage to open and close the pressure control passage; and a single solenoid that controls the pressure control valve and the shut-off valve; and a first failsafe valve provided in a first failsafe passage to apply a resistance to a flow of fluid passing therethrough. When the solenoid is not energized, the pressure control valve opens the pressure control passage and the shut-off valve closes the pressure control passage.
