A filter relief valve assembly for a simple, easy to assemble use with filter structures of the common oil filter throw away type which will function to permit oil bypass of the filter element whenever the fluid pressure exceeds a predetermined value. The assembly unit is complete unto itself, but when assembled with the other filter components support and center one end of the filter element and also center and align an associated check valve in cooperation with the filter end closure.

A filter of the throw away spin-on type having a housing body with a closed end and an open end, a filter element mounted within said body, a cover plate secured to and closing said open end, a gasket retainer secured to the end closure cover plate, fluid input and output apertures provided in both the cover plate and the gasket retainer, the gasket retainer having a recessed pocket extending circumferentially around the fluid flow openings, inwardly of the outer circumference of the gasket retainer, said gasket pocket having a base at a specified angle relative to the surface plane of the cover plate, and a resilient flexible gasket member of special shape retained by the gasket retainer pocket. The specially configured sealing gasket member is preferably of rhomboid shape and thus a cross section thereof forms a parallelogram with oblique angles and opposite sides equal. The top and bottom surfaces of the sealing gasket form an angle of approximately 10. degree.

A filter end cap interference fit structure between the internal wall of a closed end pressure vessel and the outer circumference of an end cap for centering and maintaining a filter element in position internally of the pressure vessel. The structure is arranged so as to take up and account for any differences in manufacturing tolerances of the internal parts which could destroy the proper working relationship thereof. The internal parts are solidly secured between the closed dome end of the pressure vessel and the support mounting plate of the vessel to securely hold a filter element therebetween while assuring take-up of manufacturing tolerances.
