Abstract
A disposable, spin-on fluid filter for mounting to a fluid-directing head includes a molded housing having a closed base and a sidewall defining a hollow cavity. Filtering media is positioned within the hollow cavity and a nutplate is joined to the housing so as to enclose the filtering media. The nutplate includes a plurality of inlet flow openings and a lobed sleeve extending into the filtering media. An endplate is joined to the filtering media including a flange portion and a sleeve portion. The fluid filter includes an elastomeric valve having a first portion positioned between the flange portion and the inlet flow openings and a second portion positioned between the sleeve portion and the lobed sleeve. The valve provides an anti-drain back capability and in cooperation with the lobed sleeve provides a filtering media by-pass capability.
