Spin-on filter with performance enhancement features

1. A fluid filter constructed and arranged for mounting to a fluid-directing head, said fluid filter comprising:

a housing having a closed base and a sidewall defining a hollow cavity;

a filtering media defining an open interior and being positioned in the hollow cavity;

a nutplate joined to the housing and being constructed and arranged to enclose the filtering media, the nutplate defining a plurality of inlet flow openings and further defining a sleeve extending into the open interior, the sleeve providing an exit flow conduit;

an endplate joined to the filtering media and including a flange portion and a sleeve portion; and

an elastomeric, flow-control valve having a first portion positioned between the flange portion of said endplate and the plurality of inlet flow openings and a second portion positioned between the sleeve portion of the endplate and the nutplate sleeve, wherein the first portion provides an anti-drain back capability and the second portion in cooperation with the nutplate sleeve provides a filtering media by-pass capability.

2. The fluid filter of claim 1 wherein the closed base of the housing is constructed and arranged with a one-way abutment ramp for cooperating with a bladed tool for facilitating the removal of the fluid filter from the fluid-directing head in only one direction.

3. The fluid filter of claim 1 wherein the housing is constructed and arranged with a plurality of gripping ribs for facilitating the removal of the fluid filter from the fluid-directing head.

4. The fluid filter of claim 1 wherein the housing is constructed and arranged with an annular recessed portion for cooperating with a filter removal wrench for facilitating the removal of the fluid filter from the fluid-directing head.

5. The fluid filter of claim 1 wherein the closed base of the housing is constructed and arranged with a ratchet-tooth post for cooperating with a ratchet nut for facilitating the removal of the fluid filter from the fluid-directing head.

6. The fluid filter of claim 1 wherein each inlet flow opening has a tear drop-shaped peripheral edge.

7. The fluid filter of claim 1 wherein the fluid filter includes a face seal and the nutplate includes an upper peripheral edge that is constructed and arranged with an inner annular ridge and an outer annular ridge, wherein the face seal is positioned between the inner and outer annular ridges and wherein the outer annular ridge is axially higher than the inner annular ridge for functioning as an abutment stop against the fluid-directing head.

8. The fluid filter of claim 1 wherein the flange portion of the endplate includes a plurality of flow ribs.

9. The fluid filter of claim 8 wherein the flange portion of the endplate includes a plurality of standoffs.

10. The fluid filter of claim 1 wherein the nutplate sleeve is a lobed sleeve.

11. The fluid filter of claim 1 , wherein the nutplate includes an annular crush rib that is constructed and arranged for establishing a sealed interface against the fluid-directing head.

12. The fluid filter of claim 11 , wherein the closed base of the housing is constructed and arranged with an abutment ramp for cooperating with a bladed tool for facilitating the removal of the fluid filter from the fluid-directing head.

13. The fluid filter of claim 11 , wherein the housing is constructed and arranged with a plurality of gripping ribs for facilitating the removal of the fluid filter from the fluid-directing head.

14. The fluid filter of claim 13 , wherein the housing is constructed and arranged with an annular recessed portion for cooperating with a filter removal wrench for facilitating the removal of the fluid filter from the fluid-directing head.

15. The fluid filter of claim 14 , wherein the closed base of the housing is constructed and arranged with a ratchet-tooth post for cooperating with a ratchet nut for facilitating the removal of the fluid filter from the fluid-directing head.

16. The fluid filter of claim 11 , wherein each inlet flow opening has a tear drop-shaped peripheral edge.

17. The fluid filter of claim 11 , wherein the filtering media is imbedded into the flange portion of the endplate for establishing a sealed interface therebetween.

18. The fluid filter of claim 17 , wherein the endplate sleeve portion is constructed and arranged with a size and shape that creates an interference fit around the nutplate sleeve for establishing a sealed interface therebetween.

19. The fluid filter of claim 18 , wherein the closed base of the housing is constructed and arranged with an abutment ramp for cooperating with a bladed tool for facilitating the removal of the fluid filter from the fluid-directing head.

20. The fluid filter of claim 19 , wherein the housing is constructed and arranged with a plurality of gripping ribs for facilitating the removal of the fluid filter from the fluid-directing head.

21. The fluid filter of claim 20 , wherein the housing is constructed and arranged with an annular recessed portion for cooperating with a filter removal wrench for facilitating the removal of the fluid filter from the fluid-directing head.

22. The fluid filer of claim 21 , wherein the closed base of the housing is constructed and arranged with a ratchet-tooth post for cooperating with a ratchet nut for facilitating the removal of the fluid filter from the fluid-directing head.

23. The fluid filter of claim 22 , wherein each inlet flow opening has a tear drop-shaped peripheral edge.
