Abstract

A removable and replaceable end cap that selectively lockingly engages a seat ring of a filter housing. The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element. The filter element, which may be coupled to the end cap, may be adapted to remove particulate or contaminate from the received fluid.

First claim

The invention claimed is:

1. A removable filter assembly comprising:
an end cap having a plurality of cam locking grooves and an inner wall, the plurality of cam locking grooves radially positioned about a sidewall of the end cap, each of the plurality of cam locking grooves sized to receive insertion of a pin, the plurality of cam locking grooves further structured for axial and rotational displacement, the inner wall coupled to the sidewall, the inner wall having one or more openings sized to accommodate passage of a fluid; and
a filter element having filter media, the filter media being directly bonded to the end cap and in fluid communication with the one or more openings, the filter element adapted to remove at least one of a particulate or contaminate from the fluid.

2. The removable filter assembly of claim 1 , wherein the end cap further includes a flange and a gasket member, the flange extending outwardly from the sidewall, the gasket member structured for placement about an exterior surface of the sidewall beneath the flange.

3. The removable filter assembly of claim 2 , wherein the flange is positioned to compress the gasket member against an upper surface of the seat ring when the end cap is lockingly secured to the seat ring.

4. The removable filter assembly of claim 3 , wherein the filter element is coupled to at least a portion of the inner wall.

5. The removable filter assembly of claim 4 , wherein the end cap further includes a handle, the handle extending over at least a portion of the opening of the inner wall.

6. The removable filter assembly of claim 5 , wherein the plurality of cam locking grooves include an inlet oriented to accommodate at least axial displacement of each of the plurality of cam locking grooves about the received pin as the end cap is axially displaced in a direction that is generally parallel to a central axis of the seat ring.

7. The removable filter assembly of claim 6 , wherein the plurality of cam locking grooves include a cam surface that engages a lower surface of the received pin.

8. The removable filter assembly of claim 6 , wherein the filter element is coupled to a portion of a side of the inner wall by an adhesive, epoxy, or hot melt, and wherein the removable filter assembly further includes a filter cap that is coupled to the filter element, the filter cap including a bypass valve.

9. An end cap comprising:
a sidewall having an inner surface, an opposite outer surface, an upper surface, and a lower wall; the sidewall including a plurality of protrusion receiving cam locking grooves in the outer surface, each of the cam locking grooves having an inlet extending through the lower wall of the sidewall, and each of the cam locking grooves having an inner edge spaced an axial distance from the lower wall of the sidewall;
an inner wall radially extending inwardly from the inner surface of the sidewall, the inner wall having a through-opening sized to accommodate the passage of a fluid through the end cap;
an outwardly extending flange radially extending from the upper surface of the sidewall; and a handle coupled to the inner wall and extending across the opening.

10. A high capacity filter element end cap, structured to be releasably secured to a seat ring of a filter housing including:
a sidewall having a plurality of cam locking grooves extending through an outer surface of the sidewall, each of the plurality of cam locking grooves sized to receive insertion of a pin of the seat ring and structured for axial and rotational displacement about the pin when the high capacity filter element end cap is rotated between locked and unlocked positions relative to the seat ring;
an inner wall coupled to the sidewall and having a through-opening therethrough sized to accommodate passage of a fluid through the end cap; and
a handle coupled to the inner wall and extending over at least a portion of the opening of the inner wall.

11. The high capacity filter element end cap of claim 10 , wherein:
each of the plurality of cam locking grooves includes an inlet that extends through a lower surface of the sidewall; and
the inlet is oriented to accommodate axial displacement of each of the plurality of cam locking grooves about the pin as the high capacity filter element end cap is axially displaced in a direction that is parallel to a central axis of the seat ring.

12. The high capacity filter element end cap of claim 11 , wherein each of the plurality of cam locking grooves includes an inner surface that is structured to engage a lower portion of the pin when the high capacity filter element end cap is in the locked position relative to the seat ring.

13. The high capacity filter element end cap of claim 10 , further including a flange extending outwardly from an upper surface of the sidewall.
