Abstract
Abstract A fuel/contaminant separator (10) designed to separate water and contaminants out of fuels used for products for combustion. The contaminated fuel (12) enters the fuel/contaminant separator (10) via the inlet pipe (14) located in the upper portion of the fuel/contaminant separator (10). A curved nozzle assembly (16) located at the periphery of the fuel/contaminant separator (10) cause a centrifugal effect to take place making separation similar to that achieved by elaborate mechanical centrifuges. In the collection section (26), minute particles of water and solid contaminants collect at the perforations of the perforated cone filter (28 or 38) where they accumulate and fall to the bottom of the collection section (26). The lighter fuel particles remain in suspension and flow up the center of the fuel/contaminant separator (10) to the outlet pipe (30).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A fuel/contaminant separator comprising: an inlet pipe; an outlet pipe; a curved nozzle assembly that includes a plurality of nozzles connected to said inlet pipe that guides a contaminated fuel from said inlet pipe to a separation section to form an interface due to centrifugal effect between a clean fuel and a contaminant mixture so that said contaminant mixture can collect in a collection section below said separation section wherein said collection section has a bottom and said clean fuel can rise up through said outlet pipe; a drainage valve that can be opened to release said contaminant mixture from said collection section; said separation section includes a replaceable wear sleeve; and said collection section includes a perforated cone filter where minute particles of said contaminant mixture collect at perforations of the perforated cone filter where said minute particles accumulate and fall to said bottom of said collection section.
Claim 2
Dependent Claim
149 words
A fuel/contaminant separator comprising: an inlet pipe; an outlet pipe; a curved nozzle assembly that includes a plurality of nozzles connected to said inlet pipe that guides a contaminated fuel from said inlet pipe to a separation section to form an interface due to centrifugal effect between a clean fuel and a contaminant mixture so that said contaminant mixture can collect in a collection section below said separation section wherein said collection section has a bottom and said clean fuel can rise up through said outlet pipe; a drainage valve that can be opened to release said contaminant mixture from said collection section; said separation section includes a replaceable wear sleeve; and said collection section includes a perforated cone filter where minute particles of said contaminant mixture collect at perforations of the perforated cone filter where said minute particles accumulate and fall to said bottom of said collection section.
Claim 3
Dependent Claim
19 words
A fuel/contaminant separator as recited in claim 1, wherein the perforated cone filter is supported by two support rods.
Claim 4
Dependent Claim
66 words
A fuel/contaminant separator as recited in claim 1, wherein the perforated cone filter includes a bottom support made up of a thread screw so that the perforated cone filter may be easily exchanged for a perforated cone filter of a different size so that the fuel/contaminant separator may accommodate a number of fuel grades, a number of specific gravities for contaminants, and a range of temperatures.
Claim 5
Dependent Claim
15 words
A fuel/contaminant separator as recited in claim 1, wherein the drainage valve is operated manually.
