Sept. 18, 1934. c. l. JIUSTHEIM CARBURE TOR Filed Feb. 2. 1932 gwoentot c/ar'e 11c e f Julie/F1 Patented Sept. 18, 1934 CARBURETOR Clarence I. Justheim, Salt Lake City, Utah Application February 2, 1932, Serial No. 590,493
1 Claim.
My invention relates to suction and vaporization devices and has for its object to provide a new and eflicient device for drawing the fuel from the fuel supply tank of a motor driven vehicle and mixing the fuel with the proper amount of air for complete combustion.
A further object is to provide a suction and vaporization device to replace the carburetor of today and to draw fuel from the supply tank without the use of a vacuum tank or fuel pump.
A still further object is to provide a correctly proportioned scientifically constructed suction device which through its proper proportions'will have sufficient drawing power to draw fuel and fuel vapors from the supply tank of the vehicle and which will then mix the fuel and vapors in the proper proportions with air for complete combustion in the engine of the vehicle.
These objects I accomplish with the device vi illustrated in the accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the :25! appended claim.
In the drawing in which I have shown the best and most preferred manner of building my invention Figure 1 is a diametrical section of the device.
Figure 2 is a section on line 22 of Figure 1.
Figure 3 is a section on line 3-3 of Figure 1.
In the drawing I have shown the suction device as made of a body A comprising a frustoconical chamber 1, which is joined tangentially to an outwardly curved wall 2, which in turn is connected with an outwardly flared frusto-conical chamber 3.
The walls 4 of the chamber 1 are tangential tothe radius of the circle and the ratio of the 7 length of the chamber 1 to the diameter of the smallest constriction is that of 8 to 1.
The two frusto- conical chambers 1 and 3 are reversed as to each other with the flare of the walls 4 and 5 thereof outwardly opposed to each other. Onto the end of the walls 4 of the chamber 1, I provide a flange 6 by which the entire device is secured to the intake manifold B of the engine. The end of the chamber 3 is joined to a cylindrical chamber 7 by a wall 8 which wall is made at right angles to the outer wall of the cylinder. A spring controlled butterfly valve 9 closes the open end 10 of the chamber 7 and is adapted to be opened commensurately by the suction of the engine. It will be also controlled by a lever 11 secured to the end of the shaft 12 on which the valve is supported, said lever to be controlled from the dash of the automobile for choking the device for starting the engine or for controlling the amount of opening manually, where desired.
A throttle valve 13 is mounted in the intake manifold B of the engine to control the amount of suction and thereby, the speed of the engine.
Surrounding the curved wall 2 of the device I then provide an annular distributing chamber 15 by securing two half circular sections 16 and 17 together by bolts 18 through flanges l9 and '20 formed thereon. An inlet pipe 21 connects the chamber 15 with a source of fuel supply. Ports 22 are bored through the wall 4 of the chamber 1 at the point of least constriction where the Wall 4 joins the wall 2. These ports are bored into the interior of the device at an angle preferably about fifteen degrees from the radius line. These ports connect the interior of the body A with the interior of the chamber 15, thereby introducing fuel or vapors thereinto from the chamber 15.
Another fuel pipe 24 connects an annular chamber 25 with the same or a different source of fuel supply as that to which the pipe 21 leads, and the annular chamber 25 is secured onto the end of the chamber 3 by screwing a lock nut 26 thereagainst on the threads 27 which are formed on the exterior of the wall 5. Ports 28 connect the interior of the chamber 25 with the interior of the chamber 3 adjacent the junction of the end of the chamber with the wall 8, thereby introducing fuel into the chamber 3 from the source of fuel supply. The suction of the engine drawing through the device is increased by first having to pass the constriction caused by the junction of the wall 5 to the wall 8, and in so passing the curve of the incoming air creates a suction through the ports 28 from the chamber 25 and thence from the fuel supply, and at the same time air in passing through the chamber 3 and the chamber 1 is being constricted and then expanded and the suction through the ports 25 is increased to such a deannular chamber surrounding said ports; a pipe connecting said chamber with a source of fuel supply; another row of ports through the side wall of the larger diametered chamber; an annular chamber surrounding these last mentioned ports; a pipe leading to the source of fuel supply; a cylindrical chamber on the end of the larger diametered chamber, said chamber carrying a controlled butterfly valve; and a throttle valve to control the suction through the entire device. a
