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; and
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support;
a valve body including at least one valve body projection attaching the valve body to the valve support;
a valve ball disposed between the valve body and the valve support;
a passage in the valve support keyed to the valve ball such that when a fluid pressure forces the valve ball against the passage, fluid flow through the passage is restricted; and

wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve by preventing the valve ball from contacting the passage.

2. A filter system comprising:
a designated filter cartridge including a geometric projection therein; and
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support;
a valve body including at least one valve body projection attaching the valve body to the valve support; and
a valve ball disposed between the valve body and the valve support;

wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, wherein the valve support comprises a plurality of valve support projections each having an enlarged end, each enlarged end fitting over a corresponding feature of the filter cartridge housing cover, thereby attaching the valve support to the filter housing cover.

3. The filter system of claim 1 , wherein the at least one valve body projection comprises a plurality of valve body projections, each of the plurality of valve body projections fitting over a corresponding feature of the valve support.

4. A filter system comprising:
a designated filter cartridge including a geometric projection therein; and
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support;
a valve body including at least one valve body projection attaching the valve body to the valve support; and
a valve ball disposed between the valve body and the valve support;

wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, wherein the valve body includes at least one bypass opening, the at least one bypass opening permitting fluid to pass through the valve when no filter cartridge or an incorrect filter cartridge is installed.

5. The filter system of claim 4 , wherein the at least one bypass opening comprises three bypass openings evenly spaced around a perimeter of the valve body.

6. The filter system of claim 1 , wherein the valve further comprises a valve gasket, the valve gasket including the passage keyed to the valve ball.

7. A filter system comprising:
a designated filter cartridge including a geometric projection therein; and
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support;
a valve body including at least one valve body projection attaching the valve body to the valve support; and
a valve ball disposed between the valve body and the valve support;

wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, wherein the valve further comprises a valve gasket, the valve gasket comprising a flange preventing the valve gasket from passing completely through a valve support opening in the valve support.

8. The filter system of claim 7 , wherein the valve gasket further comprising a ridge securing the valve gasket to the valve support.

9. The filter system of claim 8 , wherein the ridge engages the valve support in a snap fit connection.

10. A filter system comprising:
a designated filter cartridge including a geometric projection therein; and
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support;
a valve body including at least one valve body projection attaching the valve body to the valve support; and
a valve ball disposed between the valve body and the valve support;

wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, wherein the valve body includes a plurality of fluid flow openings separated from each other by at least one rib, the at least one rib configured so as to prevent the valve ball from passing through a respective fluid flow opening.

11. The filter system of claim 1 , wherein a valve support opening in the valve support is formed in a surface of the valve support that extends at an angle oblique to a longitudinal axis of the valve support.

12. The filter system of claim 11 , wherein the valve support may include a void area between a peripheral wall of the valve support and the surface of the valve support in which the valve support opening is formed.

13. A filter system comprising:
a designated filter cartridge including a geometric projection therein; and
a filter cartridge housing;
a filter cartridge housing cover; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support;
a valve body including at least one valve body projection attaching the valve body to the valve support; and
a valve ball disposed between the valve body and the valve support;

wherein the valve comprises an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, further comprising a sealing element engaging an outer surface of the valve support, the sealing element providing a fluid seal between the valve support and the filter housing cover.

14. A filter system comprising:
a filter cartridge housing;
a filter cartridge housing cover coupled to the filter cartridge housing; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support including at least one valve support projection attaching the valve support to the filter housing cover;
a valve body including at least one valve body projection attaching the valve body to the valve support;
a valve ball disposed between the valve body and the valve support;
a passage in the valve support keyed to the valve ball such that when a fluid pressure forces the valve ball against the passage, fluid flow through the passage is restricted;

wherein the valve comprises an opening keyed to a geometric projection of a designated filter cartridge such that when the designated filter cartridge is installed in the filter cartridge housing assembly, the geometric projection engages the opening and actuates the valve by preventing the valve ball from contacting the passage.

15. A filter system comprising:
a filter cartridge housing;
a filter cartridge housing cover coupled to the filter cartridge housing; and
a valve that controls fluid flow out of the filter system, the valve comprising:
a valve support including at least one valve support projection attaching the valve support to the filter housing cover;
a valve body including at least one valve body project
