Abstract

A filtration system comprises a housing and a shell housing removably coupled to the housing. A valve comprise a valve housing and a plunger. The plunger comprises a seal member structured to seal an opening in the valve housing. The plunger is axially movable between a closed position, in which the seal member seals the opening, and an open position, in which the seal member does not seal the opening, thereby permitting fluid to flow through the valve housing. A filter element comprises filter media and an endcap. The endcap comprises an alignment tab configured to rotationally secure the filter element with respect to the shell housing when the shell housing is received in the housing. The endcap comprise a valve interaction projection structured to transfer rotation of the filter element and the shell housing to the plunger during installation of the filter element.

First claim

What is claimed is:

1. A filter element comprising:
filter media; and
an endcap comprising an alignment tab configured to rotationally secure the filter element with respect to a shell housing during an installation of the filter element into the shell housing, the endcap comprising at least one valve interaction projection structured to transfer rotation of the filter element and the shell housing to a plunger of a no-filter no-run valve during installation of the filter element, thereby opening the no-filter no-run valve when the filter element is installed.

2. The filter element of claim 1 , wherein the at least one valve interaction projection comprises a plurality of valve interaction projections.

3. The filter element of claim 1 , wherein the endcap defines a central opening configured to allow filtered fluid to flow out of the filter element.

4. The filter element of claim 3 , wherein the at least one valve interaction projection extends at least partially through the central opening.

5. The filter element of claim 1 , wherein the endcap comprises a base extending radially over an entire axial end of the filter media, and wherein the alignment tab extends radially outwardly from an outer edge of the base.

6. The filter element of claim 1 , wherein the alignment tab is one of a plurality of alignment tabs.

7. The filter element of claim 6 , wherein the endcap comprises a base extending radially over an entire axial end of the filter media, and wherein the plurality of alignment tabs extend radially outwardly from an outer edge of the base.

8. The filter element of claim 6 , wherein the plurality of alignment tabs comprise four alignment tabs.

9. The filter element of claim 1 , wherein the at least one valve interaction projection extends along a longitudinal axis of the filter media.

10. The filter element of claim 1 , wherein the at least one valve interaction projection is at least partially radially surrounded by the filter media.

11. The filter element of claim 1 , wherein:
the endcap defines a central opening configured to allow filtered fluid to flow out of the filter element;
the endcap further comprises at least one lateral portion extending laterally into the central opening; and
the at least one valve interaction projection extends axially from the at least one lateral portion.

12. The filter element of claim 11 , wherein the endcap is a first endcap coupled to a first axial end of the filter media, and further comprising a second endcap coupled to a second axial end of the filter media opposite the first axial end of the filter media, the at least one valve interaction projection extending in a direction axially away from the second endcap.
