Self-adjusting air management valve for a filter assembly

1. A filter element, comprising:

a filter media having a first end and a second end and defining an inner annulus;

a first end cap attached to the first end of the filter media; and

an air management device disposed within the inner annulus, the air management device including:

a top portion disposed at the first end of the filter media;

a bottom portion disposed at the second end of the filter media;

a plurality of frame members extending longitudinally and connecting the top portion to the bottom portion so as to define an inner cavity located within the inner annulus; and

an air management valve including:

a base portion provided at the bottom portion;

an intake valve extending from the base portion toward the top portion, the intake valve including an elongated opening that extends along a portion of a length of the intake valve;

an exhaust valve extending axially from the base portion toward the top portion into the inner cavity, the exhaust valve extending along a longitudinal axis of the filter element; and

a fluid passage extending from the intake valve to the exhaust valve such that air and/or fuel enters into the intake valve through the elongated opening, flows through the fluid passage within the air management device from the intake valve directly to the exhaust valve, exits the exhaust valve, and is reintroduced into the inner cavity, and

wherein an amount of air introduced through the elongated opening varies based on a fluid level present within the filter element.

2. The filter element of claim 1 , wherein the elongated opening extends from a top end of the intake valve towards the base portion.

3. The filter element of claim 1 , wherein the elongated opening extends parallel to the longitudinal axis of the filter element.

4. The filter element of claim 3 , wherein the elongated opening is a slit, and a length of the slit extends parallel to the longitudinal axis.

5. The filter element of claim 4 , wherein the length of the slit is one-half the length of the intake valve.

6. The filter element of claim 4 , wherein the length of the slit is one-third the length of the intake valve.

7. The filter element of claim 1 , wherein a top end of the intake valve is closed.

8. The filter element of claim 1 , wherein the elongated opening is provided on a side facing inwardly toward the inner cavity defined by the top portion and the bottom portion.

9. The filter element of claim 1 , wherein the intake valve extends further towards the top portion than the exhaust valve.

10. The filter element of claim 1 , wherein the filter element is a fuel filter element.

11. The filter element of claim 1 , wherein the first end cap includes a central opening and the top portion includes an opening configured to align with the central opening.

12. The filter element of claim 11 , wherein the top portion further includes a rim and a sealing element received within the rim such that, when the opening aligns with the central opening, a seal is created between the air management device and the first end cap.

13. The filter element of claim 1 , further comprising a second end cap attached to the second end of the filter media, wherein the second end cap serves as a base on which the bottom portion sits such that the air management device is held upright within the inner annulus.

14. The filter element of claim 1 , wherein the air management device is removably attached to the filter element.

15. The filter element of claim 1 , wherein the air management device is permanently attached to the filter element.

16. The filter element of claim 1 , wherein the fluid passage includes a central cavity.

17. The filter element of claim 1 , wherein the fluid passage is enclosed and is continuous from the intake valve to the exhaust valve.
