Abstract
A fluid sealing gasket device for a spin-on, throwaway filter having an annular sealing gasket with a groove of a particular shape in cross-section, the groove being formed circumferentially at the outer peripheral wall thereof; a substantially correspondingly shaped annular, metal reinforcing member positioned in and extending from the correspondingly shaped groove; and an annular gasket retaining channel formed in the filter end plate for retaining the reinforced sealing gasket therein. The gasket has a lower portion positioned in the retainer channel and an upper portion extending therefrom, with the annular groove and reinforcing member located in the upper portion of the gasket. Alternatively, the reinforcing member effectively fills a "void" when the gasket is molded therearound. This fluid sealing gasket device retains the gasket's structural integrity upon installation on the filter mount and during use when high fluid pressures are exerted on the gasket from the inside of the filter. Thus this reinforced fluid sealing gasket device minimizes deformation, improper orientation, and improper displacement of the gasket during installation and use of the filter, thereby assurin…
