Fluid filter element
View Patent ↗A filter element is removably positionable within a filter housing defining a filter chamber for said filter element. The filter housing comprises a standpipe extending within the filter chamber. The filter element includes a tubular filter media circumscribing the standpipe, a first end cap supporting the filter media at one end thereof, a second end cap longitudinally spaced from the first end cap and supporting the filter media at the opposite end thereof, and a center tube extending between the first and second end caps. The center tube has at least one inlet opening therethrough, a bypass opening at a first end thereof adjacent to the first end cap and a standpipe opening at a second end thereof adjacent to the second end cap and through which the standpipe is adapted to be inserted longitudinally into the center tube.
1. A component of a filter element that engages a head and projects through one or more openings of a locking member of a flow control valve, comprising:
a center tube defined by a substantially cylindrical side portion, wherein the substantially cylindrical side portion defines an inner axial fluid flow passage, and a plurality of radial fluid passages, an end wall formed integrally with said substantially cylindrical side portion, wherein said end wall defines an axial bypass opening, a circumferential flange extending axially from said end wall within said inner axial fluid flow passage, and at least one flow control valve actuator pin extending axially from said end wall within said inner axial fluid flow passage, wherein said at least one flow control valve actuator pin engages said head and projects through said one or more openings of said locking member of said flow control valve, wherein said circumferential flange extends axially into said inner axial fluid flow passage to a distance axially beyond the axial distance that the at least one flow control valve actuator pin extends.
2. The component of a filter element as defined in claim 1 , wherein said at least one flow control valve actuator pin is disposed between said substantially cylindrical side portion and said circumferential flange, wherein said circumferential flange includes a distal end disposed within the inner axial fluid flow passage that engages an end wall of a bypass member of the flow control valve, wherein engagement of the distal end with the end wall of the bypass member of the flow control valve selectively closes off the axial bypass opening.
3. The component of a filter element as defined in claim 1 , wherein said at least one flow control valve actuator pin includes a plurality of circumferentially-spaced pins axially extending into said inner axial fluid flow passage, wherein said at least one flow control valve actuator pin is radially spaced from said axial bypass opening.
4. The component of a filter element as defined in claim 2 , wherein said circumferential flange defines said axial bypass opening.
5. The component of a filter element as defined in claim 1 further comprising a plurality of flexible fingers axially extending from said end wall.
6. A filter element that engages a head and projects rough one or more openings of a locking member of a flow control valve, comprising:
a first end cap;
a second end cap;
filter media defining all axial passage, wherein the filter media is disposed between said first and second end caps; and
a center tube integrally connected with the second end cap, wherein the center tube is axially disposed in said axial passage of said filter media, wherein said center tube is defined by an inner axial fluid flow passage, an axial end wall, and means for engaging said head and projecting through the one or more openings of the locking member of the flow control valve, wherein the means includes at least one flow control valve actuator pin extending axially from said axial end wall within said inner axial fluid flow passage, wherein said at least one flow control valve actuator pin engages said head and projects through said one or more openings of said locking member of said flows control valve.
7. The filter element according to claim 6 , wherein said center tube is defined by a substantially cylindrical side portion, wherein the substantially cylindrical side portion defines an inner axial fluid flow passage, and a plurality of radial fluid passages, wherein the end wall is formed integrally with said substantially cylindrical side portion, wherein said end wall defines an axial bypass opening, wherein said filter element further comprises
a first seal proximate said first end cap that radially seals said center tube; and
a second seal proximate said second end cap that radially seals said second end cap, and axially seals said inner axial fluid flow passage.
8. The filter element according to claim 7 , wherein said end wall includes a circumferential flange extending axially from said end wall within said inner axial fluid flow passage, wherein the at least one flow control valve actuator pin is disposed between said substantially cylindrical side portion and said circumferential flange.
9. The filter element as defined in claim 7 , wherein said at least one flow control valve actuator pin includes a plurality of circumferentially-spaced flow control valve actuator pins axially extending into said inner axial fluid flow passage, wherein said plurality of flow control valve actuator pins are radially spaced from said axial bypass opening.
10. The filter element as defined in claim 8 , wherein said circumferential flange defines said axial bypass opening.
11. The filter element as defined in claim 6 further comprising a plurality of lid interfacing flexible fingers axially extending from said end wall.
