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.
Claims7
A valve comprising:
- 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;
- an 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
- 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 different positions of the valve body in a radial direction at different heights when the valve body deflects,
- the valve case has a cylindrical case portion, the annular facing portion protruding inward in the radial direction from an inner periphery of the case portion, and
- 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 the support portion provided on an outer peripheral side among the plurality of support portions.
A valve comprising:
- a valve case;
- an annular valve body, one of an inner peripheral end and an outer peripheral end of which is a free end movable to both sides in an axial direction with respect to the valve case;
- an facing portion provided in the valve case, the facing portion including an annular facing surface which is located on an inner peripheral side or an outer peripheral side of the valve body and is configured to face the free end with a gap;
- and
- a valve stopper configured to limit an amount of a deflection of the valve body;
- and
- a spacer that is interposed between the valve body and the valve stopper,
- wherein the valve stopper has 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,
- the valve stopper has at least two stopper members having different inner or outer diameters, and
- among at least the two stopper members, the plate thickness of the stopper member abutting the spacer is larger than the plate thickness of the spacer.
