Abstract
A unitary nutplate for a fluid filter assembly provides a threaded mounting interface between an engine block mounting base and the remainder of the fluid filter assembly. The unitary nutplate is designed with an enlarged inside diameter in order to reduce the moment arm between the outer shell of the fluid filter assembly and the filtering element. With the enlarged inside diameter, the annular sidewall of the unitary nutplate does not include any flow passageways for the entering fluid and accordingly other flow passageways are created. In one arrangement, the nutplate has a generally cylindrical lower wall which cooperates with an inner seal which is designed with fluid flow passageways. In an alternate nutplate design, depending projections from the lower edge of the nutplate provide a series of flow passageways therebetween and the cooperating inner seal does not include flow passageways.
