FUEL-FEED SYSTEM FOR MOTOR VEHICLES.
@riginal application filed April 13, 1923,
My invention relates to fuel feed systems for motor vehicles, and has for its general object the provision of improved means for lifting fuel from the fuel supply tank to a carburetor mounted above the tank.
This application is a divisional part of my co-pending application 1 for patent on suction producing meansfor fuel feed systems, Serial No. 631,822, filed April 13, 1923.
In the accompanying drawings:
Figure 1 is a side elevational View of an automobile chassis showing the system of my invention; I
Figure 2 is an end elevational view of the vortex ejector employed in the system of my invention; I
Figure 3 1s a vertical cross sectional view taken along the line 33 of Figure 2, lookingiinthe direction indicated by the arrows; an
Figure 4 is a fragmentary cross sectional view showing a modified form of ejector nozzle.
Similar characters of reference refer to similar parts through the several drawings.
Referring first to Figure 1, 5 designates an automobile frame, 6 an engine mounted therein, 7 the radiator and 8 the fuel supply tank mounted at the rear of the car and below the carburetor 9. Mounted above the' carburetor 9 is the usual form of vacuum feed tank 10 arranged to draw fuel from the tank 8 through the pipe 11, From the tank 10 the fuel is permitted to flow by gravity to the carburetor 9. All of the foregoing is well known construction and needs no further explanation.
My invention relates to the means for producing the suction or reduction in pres-' sure necessary In the operation of the As shown in Figures 2 and Serial No. 631,822. Divided and this application filed October 222, 1926. Serial No. 143,364.
engine is prevented. The presence of air in the engine jackets of a water-cooling system gives rise to rapid oxidation of the jacket walls and, therefore, the accumulation of scale which. eventually clogs the system, should it find its wayto the radiator tubes. There is, also, the disadvantage caused by the formation of air pockets and their tendency to reduce the efficiency of the cooling system.
In the operation of the device, the cooling water is forced tangentially into the chamber 14 and, because of the centrifugal force produced by the vortex or whirlpool action of the water, produces a high suction at the nozzle which is used to lift fuel as described.
In Figure 4 I have shown a modified form of nozzle 17' with suction holes radiating from the center. j
Having thus described my invention, what ll claim isnew and desire to secure by Letters Patent of the United States is:
1. A fuel feed system for motor vehicles, comprising in combination an engine, a carburetor therefor, a fuel feed tank mounted above the carburetor and arranged to feed fuel thereto, a fuel supply tank below the carburetor and communicating with the feed tank, a water circulating system for .the engine, and an ejector in the circulating system located so as to receive the water as it leaves the engine for producing a suction in the feed tank.
2. A fuel feed system for motor vehicles comprising an engine, a carburetor therefor, a vacuum feed tank mounted above the carburetor and arranged to feed fuel thereto. a supply tank-below the carburetor and communicating with the fuelfeed tank. a water circulating system for the engine including a vortex chamber arranged to receive the.
water as it leaves the engine, and a nozzle 1n the chamber connected tothe fuel feed tank for the purpose of communicating a suction at the vortex to the fuel feed tank.
3. A fuel feed system for motor vehicles comprising 111 combination an a cartil buretor therefor, a vacuum feed tank mounted above the carburetor and arranged to feed fuel thereto by gravity, a fuel supply tank below the carburetor and communicat- 5 ing with the feed tank, a Water-circulating system for the engine, and an ejector in the circulating system located so as. to receive the water as it leaves the engine and connected with the fuel feed tank above the 'level of fuel therein for producing suction l I in said tank, whereby fuel is lifted from the main supply tank to the-vacuum feed tank.
In witness whereof, I hereunto subscribe my name this 19th day of October, 1926.
