Filter with water separation device
First Claim
1. A filter element for insertion into a housing, comprising:
- a tubular ring of filter media defining an internal cavity;
a first end cap sealingly secured to a first end of the filter media;
a second end cap sealingly secured to a second end of the filter media;
a portion of a water separator secured to the filter media, the portion forming an axially exposed coalescing surface facing axially away from the filter media and freely exposed when the filter element is removed from the housing; and
the portion of the water separator being less than a full water separator, the filter element requiring cooperation with another portion of the water separator, separate from the filter element, to operate to separate water from fluid flowing through the filter element.

Abstract
A filter, filter element and filter assembly are provided. The filter includes a water separating device for separating water from a dirty fluid flow. The water separator includes a fluid flow path that varies in cross-sectional area to vary pressure of the fluid therethrough. A top portion of the water separator is formed as a structurally independent piece from a bottom portion of the water separator. The top portion may be permanently or releasably secured to filter media of the filter via an end cap coupled to an end of the filter media. The bottom portion may be integrally or releasably secured to a housing of the filter. The bottom portion may also be integrally formed with a center tube upon which a filter element mounts.

12. A filter comprising:
-
a housing having a sidewall defining a central cavity; a tubular ring of filter media defining an internal cavity removably positioned within the central cavity; a first end cap sealingly secured to an end of the tubular ring of filter media defining a dirty fluid flow port; and a water coalescing cone having a top portion mounted to the tubular ring of filter media and a bottom portion mounted to the housing, the top and bottom portions combining to form a generally conical coalescing flow path therebetween in fluid communication with the dirty fluid flow port; and wherein the tubular ring of filter media is removable from the housing and the top portion of the water coalescing cone is fixedly mounted to the tubular ring of filter media such that removal of the filter media from the housing removes the top portion of the water coalescing cone from the housing while the bottom portion of the water coalescing cone remains with the housing and is reusable. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
