FUEL-SUPPLY TANK.
Applicationflled December 9, 1926. Serial No. 153,714.
This invention relates to fuel supply'tanks for internal combustion engines. and more particularly to a fuel supply tank internally equipped with a carburetting apparatus, and instrumentalities so connecting the tank and motor that, under the aspirations of the latter, a carburetted mixture of high efficiency will be automatically deliverd to the motor for combustion.
In the utilization of the structure embodying my invention, the usual form of carbureter is eliminated, and the carburetting device is positioned directly within the fuel supply tank. A valve, controlled air pipe leads into the tank, as does also the manifold of themotor, and, during the operation of the motor, air is drawn into the tank and through the gasoline contained therein, the mixed air and gasoline then being subjected to such carburctting action that a mixture of high efficiency passes into the manifold and to the motor.
. It is therefore the object of the invention -to-comb1ne with a fuel supply tank or reservoir, a carburetting apparatus mounted therein and adapted to so mix the air and gasoline that a mixture of maximum efficiency will be led into the combustion chamber of the motor.
Other objects of the invention will be made apparent in the accompanying specification, when read in connection with the drawings forming a part thereof.
In said drawings: Fig. 1 1s a long tudinal sectlon taken through a fuel tank-embodying my invention;
Fig. 2 is a section on the line 2-2 of Fig. 1.
Fig. 3 is a section on theline 3-3 of Fig. 1, and, j
Fig. 4 is a detail in perspective, showing a portion of my carburetting apparatus.
Now referring specifically to the drawmgs, in which like reference characters-midlcate like parts. throughout the several views, A indicates the usual fuel supply tank of an internal combustion engine, here shown as of rectangular formation, and 1 is an elongation of the engine manifold, extending longitudinally over the top of the tank and closely adjacent thereto. Preferably a hood 1 encloses the manifold 1. and is spaced therefrom. As shown in Fig. 1, the manifold 1 communicates with the interior of the tank A, through intakes 2, 3 and 4;. Intakes 2 and 4.- preferably comprise funnels having neck port-ions entering the manifold, the flared body portions extending into the tank A, as illustrated. The lower portion of in- It is to be understood that the manifold is provided, at some point in its length, with a butterfly valve 6 to control the flow of the mixture therethrough, and with a safety valve 7 to eliminate danger from backfire.
An air-inlet pipe 8, controlled by an adjustable valve 9, leads into the tank A adja-.
cent one end thereof, a detachable leg 10 being connected to the lower end of the pipe and positioned at the bottom of the tank,
extending longitudinally thereof, and secured in position by strap members 10, a V
strap 8' serving to secure the vertical portion of the pipe 8. A cap 11 is screwthreaded onto the end of the leg'10, being removable for cleaning purposes.
The upper face of the leg 10 of the pipe 8 is provided with a plurality of perforations 12' which are preferably punched out Wardly from the metal stock as shown, during the formation ,of the leg 10, whereby to provide upstanding flanges surrounding said perforations 12. j
The interior of the tank A may be said to be divided into compartments B, C, D and E. Compartment B is defined by which are imperforate, except as hereinafter referred to; compartment C is defined by the wall of the tank and the walls 13, and by perforated walls 14. andld' compartment walls 13, 13',
,is confined by walls 13 and the wall of the lit) ed, on the wall 16, a four sided shed 19 preferably of pyramidal configuration, the apex of which is just below the plane of the nozzles 18, andan aproned plate 20, provided with a plurality of perforations, is mounted on the apex'of said shed. Fixed on said plate 20 is a. vertically disposed baflle 21 carrying above it a protective hood 22. If desired a flat screen 23 may be provided for the top of the plate 20, as shown in the drawings.
The tank A is of air tight construction and, during the operation of the motor, the
also upwardly, through theperforations 12,
12, into the gasolinein the compartment E During this process gasoline is also en;
trained into the apertures 17 17, in the pipes 17 17, and the mixed air and gasoline is carried upwardly in said pipes and forcibly ejected through the nozzles 18, 18, against the bafie 21. The violent contact of the mixed air and fuel particles against the bafiie 21 serves to atomize the mixture, but the hood 22 serves to prevent access of any of the heavier particles through the port 3' into the intake 3, immediately above said hood. Certain of the most minutely atomized, or drier particles however, pass around said hood and enter said intake 3.
In the meantime air is also passin out of the orifices 12 and into and through t 1e main body of gasoline in the tank E, causing said gasoline to become violently agitated, and a certain amount of fuel laden air passes upwardly through the perforations in the plate 16, and through the tubes 24. It will be understood that, in the compartment B, the heavier particles offuel laden air have passed downwardly through the perforations in the screen 23 and plate 20, and drain downwardly along the sides of the shed 19,
gradually becoming lighter in this process.
The lightest particles are finally lifted by suction and subsequently pass out through lntake 3; the heavier particles continue their downward journey and pass through the perforations 19, in the sides of the shed, or
reach the perforations 19, at the base thereof, where they mingle with other upcoming fuel laden air, passing through the perforations 19 or the tubes 24, and either finally are deposited in the gasoline in compartment E, or passupwardly again and,
eventually, out through the intake 3, dependent upon their condition of carburation,
It is to be noted that the perforations in ,the top and bottom walls defining the compartments C and D, are arranged so that the perforations on the one Wall are staggered with respect to those on the other wall.-
While carbui'ation is taking place in the tions are out of line with those in the lower '7 plate, and the same process is carried out duringthe passage of the fuel laden particles through the platel i, and finally out through the intakes 2 and 4. In all cases the light particles are retained until they are broken up orrarefied sufiicientlry to pass out of the intakes. It is throughithis continuous agitation and separation of the mixed particles of air and gasoline, together with the boil ing action caused by the passage of the air through the gasoline in the tank E, and the constant impingement of the mixed particles upon baflies in its upward path, that the production of' a fuel of maximum efiicie'ncy is possible.
It is to be noted that there is no communication between compartments B and the other carburetting compartments or chainbers, and that all the mixture which enters compartment B passes into the manifold through the port 3. Compartments C and l) are virtually one chamber, with a perforated baffle wall 15' separating them .to break up the mixed particles of air and gas,
and permit the lighter particles to finally pass out of the ports 2 and 4, on each side of the compartment B.
The drier gas is produced; in the central compartment B, because of the violent'im- 'pingement of the mixed air and'gas globules upon the baffle 21, from the nozzle 18, and
the provision of the shed 19. with its down I Wardly inclined walls which permit slowgravitation of the heavier particles until 3 they become more rarefied.
The tank A is filled through the usual port 25, and may be drained through the pet-cock 26. I
