The fuel filter assembly for filtering and removing water from a fuel under pressure includes an outerhousing, an inner sleeve member, an annular space between the outerhousing and the inner sleeve member, and filtering media for filtering the fuel. The filtering media is positioned within the sleeve member. The fuel inlet is at the upper end of the outer housing and provides fluid flow between the outer housing and the inner sleeve. The fuel inlet and annular space are positioned and dimensioned to provide a downward, non-circumferential, substantially laminar flow in the annular space. The inner sleeve member extends downwardly to a position below the bottom of the filtering media. The downwardly flowing fuel and contaminants must turn 180 degrees and flow upward through the filter media to the outlet. The slow moving denser components settle out in the accumulation chamber. The accumulation chamber is the region within the lower end of the outerhousing, below the filter media and the annular sleeve. The outlet valve provides a fluid drain for materials which accumulate in the accumulation chamber. The filtering media can be a hydrophobic filter media that prohibits the passage of water through the filter media.

[ What is claimed is:] [1.] A liquid separation assembly for use in separating and removing a first material from a first liquid under pressure comprising:an outerhousing,an inner sleeve member,an annular space between the outerhousing and said inner sleeve member, filtering means for filtering said first material from said first liquid, said filtering means being positioned in said inner sleeve member;an inlet flow port, said inlet flow port at the upper end of said outer housing and providing inlet fluid flow of said first liquid and said first material, to an annular region between said outer housing and said inner sleeve member, said inlet port and annular space being positioned and dimensioned relatively, to direct fluid flow downward in said annular space, and provide a downward, non-circumferential, substantially laminar flow in said annular space,said inner sleeve member extending downwardly to a position below the bottom of said filtering means;an accumulation chamber, said accumulation chamber being positioned within the lower end of said outerhousing,liquid outlet valve means, said outlet valve means providing a fluid drain for said first material which accumulates in said accumulation chamber, anda first liquid outlet port, said first liquid outlet port being positioned interior of said inner sleeve member and proximate the upper end of said inner sleeve member so that said liquid must traverse said filtering means before exiting through the liquid outlet port,whereby fluid enters said liquid separation assembly downwardly, flows downwardly, in a laminar, non-circumferential flow, within said annular space, causing the separation of said first material from said first liquid, and said first liquid flows vertically upward through said filtering means in said inner sleeve member, to said first liquid outlet port.
