Abstract

A filter assembly that includes a separator for separating gas from a fluid. The assembly includes; a base with surrounding walls that define a fluid reservoir; a baffle that overlies at least a portion of the reservoir; a filter element that is beneath the baffle and in the reservoir; and, a cover that is removably fastened to the base and includes a fluid inlet that terminates in a conical base with an unrestricted opening and the baffle includes a fluid impact cone.

First claim

What is claimed is:

1 . A filter assembly comprising:
a base with surrounding walls that define a fluid reservoir;
a filter element positioned within the reservoir; and
a separator for separating gas from a liquid, the separator including:
a baffle with an outer perimeter that overlies at least a portion of the reservoir; and
a removable cover that is fastened to the base and defines a fluid inlet that terminates in an open base;
wherein the baffle includes a closed recess that is spaced from the open base of the removable cover and is surrounded by an upstanding ring and a semi-circular portion of the outer perimeter of the baffle.

2 . The filter assembly of claim 1 , the cover further comprising an outer perimeter wall having a rounded section that meshes with the semi-circular portion.

3 . The filter assembly of claim 1 , the baffle further comprising a perimeter wall that meets both the upstand ring and the semi-circular portion.

4 . A filter assembly that includes a separator for separating gas from a liquid, the assembly comprising:
a base with surrounding walls that define a fluid reservoir; a baffle that overlies at least a portion of the reservoir, the baffle concentrically including a flat ring, an upstand ring, and a wall; a filter that is beneath the baffle and in the reservoir; a removable cover that includes a fluid inlet upstream from the filter and a fluid outlet downstream from the filter; a plurality of fasteners for joining the removable cover and the base; and, a plurality of separable connections for holding the baffle on the removable cover; wherein the cover cooperates with the flat ring, the upstand ring, and the wall to form the separator and the fluid inlet terminates in a conical base with an unrestricted opening.

5 . The filter assembly of claim 4 , wherein the plurality of separable connections provides a releasable press fit.

6 . A separator for separating gas from a liquid in a filter assembly, the separator comprising:
a base with surrounding walls that define a fluid reservoir; a baffle with an outer perimeter that overlies at least a portion of the reservoir; and a removable cover that is fastened to the base and defines a fluid inlet that terminates in an open base; wherein the baffle includes a closed recess that is spaced from the open base and is surrounded by an upstand ring and a concentric semicircular wall of the outer perimeter of the baffle.

10 . The separator of claim 6 , wherein the closed recess is coaxial with the open base and terminates in a closed lower end.

11 . The separator of claim 6 , wherein an outer perimeter wall of the removable cover and the semicircular wall of the baffle mesh to delineate the separator.
