Filter with ejection mechanism
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.
1. A filter element, comprising:
a ring of filter media having opposed first and second ends, an inner-most periphery defining an inner diameter of the ring of filter media, and an outer-most periphery defining an outer diameter of the ring of filter media;
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 an inlet 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 inlet flow port; and
wherein the second end cap construction includes an end cap portion and an ejector receiver configured to receive the actuation of an ejector, the ejector receiver including an axially extending annular flange formed integrally with the end cap portion, the axially extending flange extending axially away from the end cap construction and terminating in an annular free end, the annular free end being radially outward of the inner most periphery of the ring of filter media such that the annular free end is configured for axial engagement with the ejector radially outward of the inner most periphery of the ring of filter media upon actuation of the ejector.
2. The filter element of claim 1 , wherein the axial free end of the annular flange forms an axial most extent of the filter element.
3. The filter element of claim 2 , wherein the ejector receiver is formed integrally with the end cap portion as a single, continuous component, wherein the ejector receiver is not separable from the second end cap construction.
4. The filter element of claim 3 , wherein the annular flange extending axially from the end cap portion of the second end cap construction, has a curved outer periphery.
