Abstract
The valve includes a valve case; an annular valve body, an outer peripheral end of which is a free end movable to both sides in an axial direction with respect to the valve case; a facing portion provided in the valve case, the facing portion including an annular facing surface which is located on an outer peripheral side of the valve body and is configured to face the free end with a gap; and first and second valve stoppers which are located on both sides respectively in the axial direction of the valve body. The first and second valve stoppers, respectively, have a plurality of support portions that are configured to support different positions of the valve body in a radial direction at different heights when the valve body deflects.
Claims10
A valve comprising:
- a valve case;
- an annular valve body, an outer peripheral end of which is a free end movable to both of opposite sides in an axial direction with respect to the valve case;
- an annular facing portion provided in the valve case, the facing portion including an annular facing surface which is located at an outer peripheral side of the valve body and is configured to face the free end with a gap between them;
- and
- a valve stopper configured to limit an amount of a deflection of the valve body, wherein
- the valve stopper has a plurality of support portions that are configured to support the valve body from a same one of the opposite sides in the axial direction, at positions different from one another both in a radial direction and in the axial direction,
- the valve case has a cylindrical case portion, the facing portion protruding inward in the radial direction from an inner periphery of the case portion,
- a diameter of the free end of the valve body is larger than a diameter of an outer peripheral edge of the valve stopper, the outer peripheral edge being one of the plurality of support portions that is provided on an outermost peripheral side among the plurality of support portions, and
- the outer peripheral edge of the valve stopper abuts a vicinity of the free end of the valve body to support the valve body when the valve body deflects.
