Abstract

A filter system including a designated filter cartridge including a geometric projection therein and a filter cartridge housing. The filter cartridge housing including a valve that controls fluid flow out of the filter system, a filter cartridge housing, and a filter cartridge housing cover. The valve may include an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, and the valve may be configured to attach to the filter cartridge housing cover by a snap fit connection.

First claim

What is claimed is:

1. A filter system comprising:
a designated filter cartridge including a geometric projection therein;
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system,
wherein the valve comprises:
a valve body;
a valve support; and
a valve ball;

wherein the valve body includes projections configured to attach the valve body to the valve support by a snap fit connection, the valve support includes projections configured to attach the valve support to the filter housing cover, and the valve ball is disposed between the valve body and the valve support, and wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, and wherein the valve is configured to attach to the filter cartridge housing cover by a snap fit connection.

2. The system of claim 1 , wherein the valve includes at least two fluid flow openings and a rib separating the fluid flow openings, and wherein the rib is configured to prevent the ball from extending through the fluid flow openings.

3. The system of claim 1 , wherein the valve body includes at least two walls that extend inward from a peripheral wall of the valve body,
wherein the walls are configured to define the area in which the ball may travel.

4. The system of claim 1 , wherein the valve support includes a ball opening,
wherein the ball opening is formed in a portion of the valve support that extends at an angle oblique to a longitudinal axis of the valve support.

5. The system of claim 1 , wherein the valve comprises a sealing element, and wherein the sealing element is configured to produce a seal between the valve support and the filter housing cover, the seal separating unfiltered fluid from filtered fluid.
