An evaporative emissions filter for an engine air induction system. The evaporative emissions filter includes a hydrocarbon vapor-adsorbent member disposed within the air induction system outside the direct air flow path. A mechanism is provided for mounting the evaporative emissions filter within the air induction system. Hydrocarbon vapors present in the air induction system after engine shut-down are substantially retained in the adsorbent member until air flows through the air induction system after the engine starts.

An improved sealing grommet for a spin-on type fluid filter has an annular flange coupled to an interior wall of the grommet body which sealingly engages filter adapter standpipes of varying diameters. An annular cavity, formed by the interior wall of the grommet body and the annular flange, allows pressurized fluid within the annular cavity to exert forces against the surface of the cavity to thereby enhance the sealing engagement between the filter element, the base plate and the filter adapter standpipe.

In a fluid filter, magnetic filtration of ferrous particles is provided by an adhesive having magnetic properties which is placed within a filter assembly in either a structural or nonstructural capacity.

Contaminant filter with magnetic filtration capabilities

A flexibly resilient sealing member, incorporating integral pressure relief valves, for use in an oil filter assembly, includes a substantially annular body formed from a flexibly resilient material. The annular body has a central bore formed therein for surrounding an oil filter outlet. The annular body also has an upper surface with a plurality of normally closed slits formed therein, a shoulder portion around its top outer edge for sealing placement inside a cylindrical filter element, and a flow channel formed therethrough for each of the normally closed slits, each of the flow channels extending downwardly from one of the normally closed slits and terminating in an open inlet below the shoulder portion and outside of the central bore. The sealing member according to the present invention may further include an integral pedestal ring attached to the lower surface of the annular body adjacent the annular bore and extending downwardly therefrom, and a transverse flange attached to the outer surface of the annular body below the shoulder portion, and extending outwardly therefrom to limit entry of the sealing member into a filter element. In this embodiment, preferably, each of the flow channels extends from a bottom surface of the annular body above the pedestal ring, through the annular body; and communicates with one of the normally closed slits in the top surface of the annular body. The present invention also encompasses an oil filter assembly incorporating the sealing member thereof.
