engine water jacket and the radiator. As shown in Figures 2 and 3 this ejector is made up of a casing 13 arranged to provide a vortex chamber 14, a water inlet 1 5'tangent to the chamber 14, and a water outlet 16 concentric with the chamber. Extending int-o thechamber 14: and concentric therewith is an ejector .or nozzle 17 arranged for a pipe fitting at 18 for the urpose of communicating the suction prodiiced at the nozzle to the vacuum feed tank, as shown at 19 in Figure l.
In the operation of the device, the cooling water is'forced tangentially into the chamber 14 and, because of the centrifugal 4 force produced "by the vortex or whirl-pool action of the'vvater, produces a high suction at the nozzle which is used to lift fuel as described. I v
in Figure 4 I have shown a modified form of nozzle 17' with suction holes radiating from the center Having thus described my invention, what I claim is newand desire to secure by Letters Patent of the United States is:
A suction producing device adapted to be My invention relates to suction producing means for fuel feed systemsfor automobiles, and has for its general object the provision of improved means for lifting fuel from a fuel supply tank to'a carburetor mounted above the tank. I
In the accompanying drawings:
Figure 1 is a side elevational view of an automobile chassis showing the system of my invention;
' Figure 2 is an end elevational view of-the vortex ejector employed in the system of my invention;" I Figure 3 is a vertical cross sectional view taken alongthe line 3-3 "of Figure 2, looking in the direction indicated by the arrows; and A i Figure 4 is a fragmentary cross sectional view showing -a modified form of ejector nozzle. I 4
Similar characters of reference refer to similar partsthrough the several drawings. I Referring first-to Figure 1, 5' designates an, automobile frame, 6 an engine mounted therein, 7 the radiator and 8 the fuel pp y. 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 LOarranged to draw fuel fromthe tank 8 through the pipe 11 From thetank 10 the fuel is permitted toflow by gravity to the carburetor 9. Allof the foregoin is well-known construction and needs no ur-- ther explanation.
My invention relates to the means for producing the suction or reduction in pressure necessary in the operation of' the vacuum feed tank and comprises the use of a vortex ejlector in "the water-circulating system of t e engine. lnFigure 1, 12
r designates a vortex e ector forimng part of the water circulating system extending between the inserted in the pressure circulating water system of an internal combustion engine, comprising a vortex conduit having intake and discharge openings and conformed to receive water tangentially from the intake opening and imparting a spiral motion thereto, the conduit having an increasing 7,
constriction longitudinally from the intake for progressing the water with increased velocity toward the discharge end of the casing in its spiral movement, and a suction duct terminating adjacent the region ofincreased velocity for supplying-suction.
In witness whereof, I hereunto subscribe 1 my name this 27th da of March,.1923.
