Abstract

A coupling filter for a fluid system comprising a molded hollow tubular body having a wall defining a flow passage, a porous filter element of generally parabolic cross-sectional shape with a base portion extending across the entire flow passage and a pair of wing portions extending longitudinally of the flow passage and converging toward the base portion. In one form the base portion is cylindrical and in another form it is “W” shaped with a series of flat mesh panels presented to the flow path.

First claim

The invention claimed is:

1. A coupling filter for a fluid system comprising:
a wall defining a hollow tubular body along a longitudinal centerline defining a flow passage between its ends, wherein said wall of said body is formed of molded polymeric material;
a porous filter element disposed between said ends of said body and integrated into said body, wherein said porous filter element includes an outer peripheral edge secured in fluid tight relation within the wall of said body, wherein said peripheral edge of said porous filter element is embedded in said molded polymeric material;
wherein said porous filter element has a parabolic cross-sectional shape including a base portion extending across said entire flow passage and a pair of wing portions extending therefrom.

2. A coupling filter as claimed in claim 1 wherein said wing portions converge in the direction of flow from said wall of said body defining said flow passage to said base portion.

3. A coupling filter as claimed in claim 2 wherein said wing portions converge in the direction of flow from said wall of said body defining said flow passage to said base portion.

4. A coupling filter as claimed in claim 2 wherein said base portion is generally cylindrical in shape about a centerline perpendicular to a plane passing through the longitudinal centerline of said body and extends across the entire flow passage.

5. A coupling filter as claimed in claim 3 wherein said base portion is generally cylindrical in shape about a centerline perpendicular to a plane passing through the longitudinal centerline of said body and extends across the entire flow passage.

6. A coupling filter as claimed in claim 1 , said body defines a coupling having an exterior barb at each end.

7. A coupling filter as claimed in claim 6 wherein said body defines an exterior abutment spaced between said barbs at said ends.

8. A coupling filter as claimed in claim 3 wherein said porous filter element comprises a stainless steel mesh.

9. A coupling filter as claimed in claim 8 wherein said stainless steel mesh is insert molded into said wall of said body.

10. A coupling filter as claimed in claim 1 wherein said wing portions converge toward said base portion.

11. A coupling filter as claimed in claim 2 wherein said wing portions converge toward said base portion.
