Abstract
A compression-type valve seating ring device for sealingly engaging the valve seat. The seating ring device includes a resilient cylindrical body having a central axis and having a side surface, a top surface and a bottom surface. A first inward bevel is defined circumferentially from the side surface toward the top surface, and a second contour is defined circumferentially between the first bevel and the top surface, wherein the first bevel provides a seating surface and the second contour enhances the seal and life of the valve. The valve element is configured symmetrically such that top and bottom sides are substantially identical.
Claims8
A compression-type valve comprising:
- means defining a first space to which fluid may be supplied;
- means defining a second space to which the flow of fluid is to be controlled;
- a seating ring interposed between said means defining said first and second spaces;
- and
- valve means for sealingly engaging the seating ring including a resilient cylindrical body having a central axis and having a side surface, a top surface and a bottom surface, a first inward bevel being defined circumferentially from the side surface toward the top surface, a second contour defined circumferentially between the first bevel and the top surface, a third inward bevel being defined circumferentially from the side surface toward the bottom surface, and a fourth contour defined circumferentially between the third bevel and the bottom surface.
