Abstract
Abstract The invention is related to a fuel purifying apparatus, especially diesel fuel, which consists in a hollow cylindrical body that has a fuel intake orifice and an exit orifice through which the fuel, respectively, enters the apparatus to be purified, and leaves in the direction of the vehicle engine with increased purity properties; a fuel flow conduit in fluid communication with the intake orifice, solidly arranged on the inner wall of the cylindrical body and whose fuel discharge orifice is next to a metal deflector plate that extends diametrally and also substantially in a longitudinal manner, in the interior of the cylindrical body; and an electric heating element that partially penetrates the cylindrical body through an insertion orifice made in said body, the inner end of the heating element being near the deflector plate to heat it. In addition, the apparatus incorporates drainage elements for withdrawing from the apparatus the impurities separated out of the fuel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A fuel purifying apparatus for a vehicle's engine comprising: a hollow body having an upper and a lower portion; a fuel intake orifice, in the upper portion, in fluid communication with a fuel supply; an interior fuel flow conduit within the hollow body and in fluid communication with the fuel intake orifice, said fuel flow conduit having a fuel discharge orifice positioned below the fuel intake orifice; a generally flat heat conducting deflector plate located inside the body adjacent to the fuel discharge orifice and connected to a heat source, a longitudinal axis of the plate being positioned parallel to a longitudinal axis of the body and angled relative to the fuel discharge orifice so that fuel discharged from the discharge orifice contacts the plate to create a centrifugal current thereby causing turbulence which separates impurities from the fuel; and a fuel exit orifice, in the upper portion, in fluid communication with the vehicle's engine and the purified fuel within the body.
Claim 2
Dependent Claim
162 words
A fuel purifying apparatus for a vehicle's engine comprising: a hollow body having an upper and a lower portion; a fuel intake orifice, in the upper portion, in fluid communication with a fuel supply; an interior fuel flow conduit within the hollow body and in fluid communication with the fuel intake orifice, said fuel flow conduit having a fuel discharge orifice positioned below the fuel intake orifice; a generally flat heat conducting deflector plate located inside the body adjacent to the fuel discharge orifice and connected to a heat source, a longitudinal axis of the plate being positioned parallel to a longitudinal axis of the body and angled relative to the fuel discharge orifice so that fuel discharged from the discharge orifice contacts the plate to create a centrifugal current thereby causing turbulence which separates impurities from the fuel; and a fuel exit orifice, in the upper portion, in fluid communication with the vehicle's engine and the purified fuel within the body.
Claim 3
Dependent Claim
11 words
The apparatus of claim 1 wherein the body is cylindrically shaped.
Claim 4
Dependent Claim
14 words
The apparatus of claim 2, wherein the heat conducting plate is made of metal.
Claim 5
Dependent Claim
43 words
The apparatus of claim 3, wherein the interior fuel flow conduit is an elongated pipe whose perpendicular arrangement with respect to a longitudinal axis of the intake orifice allows a first impact of the fuel that enters the apparatus through the intake orifice.
Claim 6
Dependent Claim
25 words
The apparatus of claim 3, wherein the deflector plate is heated by an electrical resister within the body that is in contact with the plate.
Claim 7
Dependent Claim
44 words
The apparatus of claim 3, wherein there is a first valve for draining the impurities separated out from the fuel and a second venting valve that withdraws the gases from the interior of the apparatus and also facilitates the draining operation of the apparatus.
Claim 8
Dependent Claim
175 words
A fuel purifying apparatus for a vehicle's engine comprising: a hollow body having an upper and a lower portion; a fuel intake orifice, in the upper portion, in fluid communication with a fuel supply; an interior fuel flow conduit within the hollow body and in fluid communication with the fuel intake orifice, said fuel flow conduit having a fuel discharge orifice positioned below the fuel intake orifice, a longitudinal axis of the interior fuel flow conduit being positioned parallel to a longitudinal axis of the body; a heat conducting deflector plate, adjacent to the fuel discharge orifice and connected to a heat source, a longitudinal axis of the plate being positioned parallel to the longitudinal axis of the body and angled relative to the fuel discharge orifice so that fuel discharged from the discharge orifice contacts the plate to create a centrifugal current thereby causing turbulence which separates impurities from the fuel; and a fuel exit orifice, in the upper portion, in fluid communication with the vehicle's engine and the purified fuel within the body.
