ATTE RNEYS Patented July 10, 1951 UNITED STATES PATENT OFFICE 1 Claim.
The present invention relates to an improved fuel vaporizer particularly adapted for use in internal combustion engines using gasoline as a fuel and consists generally in the unique filter inserted between the carburetor and the intake manifold of the engine and other novel combinations and arrangements of parts as will be hereinafter fully described.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.
In the drawings:
Figure 1 is a front elevational view of the housing for the filter of my invention.
Fig. 2 is a vertical sectional View at line 2 2 of Fig. 1.
Fig. 3 is a partial longitudinal sectional view at line 3 3 of Fig. 2.
Fig. 4 is a horizontal sectional view at line 4-4 of Fig. 3.
Fig. 5 is a horizontal sectional View at line 5 5 of Fig. 3.
Fig. 6 is a horizontal sectional view at line 6-6 of Fig. 3.
Fig. 7 is a top plan view of the filter.
Fig. 8 is a perspective view thereof.
Fig. 9 is a perspective view of a diffusing device.
Fig. l is a sectional view of a modified ported stud; and
Fig. l1 is a diagrammatic View showing the electrical circuit for heating the lter.
Referring now to the drawings I have illustrated the present embodiment of my invention as mounted upon a conventional engine 2 having an exhaust manifold 4 and exhaust pipe 6. A butterfly valve 8 on shaft I0 is actuated by a heat responsive coil I2 secured in the stud I4 through slot I5, and the nut portion Ia permits the stud to be tightened into the intake manifold I6.
The intake manifold I6 has the usual pipes I1 secured to the engine by bolts I8 and the manifold is fashioned with a fiat wall 20 over the exhaust manifold, the valve 8 controlling the flow of hot exhaust gases in contact with the wall 20.
A cap 30 is secured to the casing 24 by bolts 25 and the interior of the cap is fashioned with a dome recess 32 and an upper port 34 to a conventional carburetor 36 having a recessed ange 31.
On the seat 28 I utilize a filter 38 comprising a hollow cone of pressed powdered metal and porous to permit the flow therethrough of the gasoline and air mixture from the carburetor while filtering impurities and foreign objects. The flange 49 is pressed into the cap 30 for tight fit therein and resting upon the seat 28.
The cap and casing form an atomizing chamber in which the filter is located and to create turbulence within this chamber I employ a stem 42 positioned in and above the wall 28 and having a disk 44 preventing the stem from slipping through the wall, and spaced cones 46 and 48 diverge the gas and air fiow while the venturi 21 constricts the flow.
In Fig. 1l I have shown how the cone filter of my invention `may be used in the intake pipes I1, the wires 52 leading to the top 54 of the cone and the connector 56 thereon from the switch 50 and battery 60 and ground 62 thereby permitting the heating of the porous metal filter by electricity.
In Fig. lO I have shown the stud I4 with a passage 64 communicating with the atomizing chamber, and the outlet 66 being controlled by a ball valve 88 inside the end of the pipe or tube 10.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:
A fuel vaporizer comprising, a casing forming an atomizing chamber, an intake chamber below and connecting with the atomizing chamber, intake openings for said intake chamber, a porous metal filter having a hollow conical formation, within said atomizing chamber, a diffusing cone within and aligned with the base of said hollow filter and extending into said atomizing chamber, a second diffusing cone below said first diffusing cone and connected thereto and lying within the intake chamber opposite to one of the intake openings for said intake chamber, and a heat transfer means for heating the porous metal lter.
