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 filter arrangement comprising:
(a) a filter housing and a plurality of pins protruding inwardly therefrom;
(b) a filter assembly for use with the filter housing; the filter assembly including:
(i) a pleated media pack forming an interior;
(ii) a first end cap secured to a first end of the pleated media pack;
(iii) a filter cap secured to an opposite second end of the pleated media pack;

(c) wherein the first end cap includes:
(i) an external sidewall and a center opening in communication with the interior of the pleated media pack;
(ii) an outwardly directed gasket around and against the external sidewall; and
(iii) a plurality of radially spaced locking grooves in the sidewall and axially between the gasket and the filter cap; each of the locking grooves positioned about the sidewall and structured to receive one of the pins; each of the locking grooves having an inlet for one of the pins extending through a lower wall of the sidewall, the lower wall being at an end of the sidewall adjacent the pleated media pack and axially between the gasket and the filter cap.

2. The filter arrangement of claim 1 wherein the plurality of radially spaced locking grooves includes four locking grooves.

3. The filter arrangement of claim 1 wherein the plurality of radially spaced locking grooves includes four evenly spaced locking grooves.

4. The filter arrangement of claim 1 wherein the pins are part of a seat ring of the filter housing.

5. The filter arrangement of claim 1 wherein the first end cap further includes a circumferential flange projecting radially outwardly from the sidewall.

6. The filter arrangement of claim 5 wherein the gasket is positioned axially between the flange and the locking grooves.

7. The filter arrangement of claim 5 wherein the gasket is positioned against a radial surface of the flange.

8. The filter arrangement of claim 1 further comprising an inner wall angled relative to the sidewall and projecting radially inwardly.

9. The filter arrangement of claim 1 , wherein the first end cap further includes a handle, the handle extending over at least a portion of the opening.

10. The filter arrangement of claim 1 , wherein each of the locking grooves includes a cam surface positioned to engage a lower surface of one of the pins.

11. The filter arrangement of claim 1 , further including one of an adhesive, epoxy, or hot melt securing the pleated media pack to the first end cap.
