1. A filter element, comprising:
- a ring of filter media having opposed first and second ends;
a first end cap construction including a first disc region sealingly connected to a first end of the filter media, the first end cap having a flow port;
a second end cap construction sealingly connected to a second end of the filter media;
a center tube having an inlet flow passage connecting an inlet of the filter element and the flow port;
an ejector receiver configured to receive the actuation of an ejector, the ejector receiver formed integrally with the second end cap construction and forming a distal end thereof, wherein the ejector receiver is disposed radially outward of an inner most periphery of the ring of filter media;
wherein the ejector receiver is an annular flange extending axially from an end cap portion of the second end cap construction, in a direction extending axially away from the ring of filter media; and
wherein the annular flange forms a radially outermost rim portion of the second end cap construction.

Abstract
A filter system having a filter element ejection device is provided. Filter systems according to the present invention may include a filter element that includes an ejection receiver for receiving actuation action from an ejector of a filter housing. The ejector engages the ejection receiver when a user desires to eject the filter element from the filter housing. Typically, the ejector extends through the filter housing and axially ejects the filter element from the housing.

3. A filter element for use with a housing having an ejector button, the filter element adapted to be pushed out of the housing in response to actuation of the ejector button when mounted in the housing, the filter element comprising:
-
a ring for filter media having opposing first and second ends, the first end disposed above the second end; a center tube having an inlet flow passage fluidly communicating the first end with the second end; a pair of end caps sealingly secured to the opposing first and second ends of the ring of filter media, respectively; an ejector receiver adjacent the second end of the ring of filter media for responding to the actuation of the ejector button for facilitating ejection of the filter element, the ejector receiver extending to a distal end which is disposed below the second end of the filter media, wherein the ejector receiver is disposed radially outward of an inner most periphery of the ring of filter media; wherein the ejector receiver is an annular flange extending axially from the second end cap in a direction extending from the ring of filter media; and wherein the annular flange forms a radially outermost rim portion of the second end cap. - View Dependent Claims (4, 5)
