Coalescing filter assembly
First Claim
1. A filter arrangement for use with a vessel containing pressurized fluid, the arrangement comprising:
- a body engageable with the vessel, the vessel having a pressure differential between an inside of the vessel and an outside of the vessel;
a coalescing filter assembly for removing entrained liquid from the pressurized fuel, having a housing defining a cavity for supporting a coalescing filter and supported by the body such that the coalescing filter assembly is disposed inside the vessel when the body is engaged with the vessel, the coalescing filter assembly having substantially the same pressure as the inside of the vessel; and
valve means positioned between the outside of the vessel and the coalescing filter assembly for maintaining the pressure differential between the inside of the vessel and the outside of the vessel.

Abstract
A filter arrangement for use with a vessel containing pressurized fluid includes a body engageable with the vessel. The arrangement further includes a coalescing filter assembly supported by the body such that the filter assembly is disposable inside the vessel when the body is engaged with the vessel. In one embodiment of the filter arrangement, the coalescing filter assembly includes a housing having a cavity, a coalescing filter disposed in the cavity for removing entrained liquid from the fluid, and a drain device in fluid communication with the cavity for draining the liquid removed by the coalescing filter from the cavity into the vessel.
