tem particularly adapted to supply fuel under pressure to aircraft engines and having a jet booster pump arranged to vtake fuel from the fuel tank runtil substantially dry, and having a positive pressure means by-passing fuel from the engine fuel pump and supplying fuel at a high pressure and velocity to said jet booster pump.
Another object of our Ainvention is to provide means of a simplified form and arrangement adapted to completely scavenge material from a tank or casing.
A further object of our invention is to provide a fuel system particularly adapted to supply fuel under pressure to aircraft engines wherein all of the high pressure lines of the system are protected to prevent loss of fuel therefrom in case of rupture of any of said lines.
A still further and more specific object of our invention is to provide a fuel system for aircraft engines having a high pressure line adapted to supply fluid under pressure to the engine and a self-sealing low pressure line connected to return fuel which may leak from said high pressure line, for use by the engine.
A further and more specific Vobject of this invention is to provide a fuel system for aircraft engines wherein a power-driven fuel pump is ."f;
used to supply fluid under pressure to the engine, a -iet pump is provided in the fuel tank for the engine to boost the intake pressure Ato said fuel pump, and an independent pump is utilized to bypass fuel from the intake side of said fuel pump and supply fluid under a high pressure and velocity to the jet pump to assure a constant supply of fuel to the engine under various atmospheric conditions and until the fuel tank of the engine is substantially dry.
These and other objects of our invention will appear from time to time as the following speciication proceeds and 'with reference to the accompanying drawings wherein:
Figure 1 is a diagrammatic view of a fuel system constructed in accordance with our invention;
Figure 2 is a cross-sectional view `taken through a coaxial high pressure and low pressure fuel line constructed in 4accordance with our invention; and
Figure 3 is a diagrammatic view illustrating a modified form in which our invention may be utilized.
As shown on the drawings:
In Figure 1 of the drawing, the reference character IG designates generally a tank for fuel with a top wall II having a vent therein. The tank I0 is also shown as having a bottom wall I2 having a sump I3 therein, with a high pressure line Il for a high pressure jet I5 of a jet pump I6 leading through an opening I 'I in said tank.
The high pressure jet I5 is shown as extending within the mouth of a venturi I8 of the jet booster pump I6 for boosting kthe pressure in an intake fuel line 20 leading from the bottom of said tank to a main engine fuel supply pump 2|.
A high pressure fuel supply line 22 leads from the discharge side of said pump 2| to an aircraft engine 23 for lsupplying fuel under pressure thereto.
The aircraft engine 23 may be of any well known form commonly used to propel aircraft and is herein shown as being an in-line engine having a crank shaft 2B. A suitable drive means 25 is shown as connecting said crank shaft to said main engine fuel pump 2I to drive said pump therefrom. Said drive means may be of any well known form commonly used to drive pumps from internal combustion engines such as a chain and sprocket drive or a well known form of V-belt drive.
A by-pass line 25 is connected from the fuel intake line 20 for the pump 2I to the intake side of a high pressure pump 27 adapted to supply fuel at a high pressure and velocity to the jet booster pump I6. A valve 29 is connected in the by-pass line 26 and controls the passage of fuel to said high pressure pump 2l. The high pressure line I Il connects the discharge side of said high pressure pump 2l to the high pressure jet I5 for supplying fuel thereto at a high pressure and velocity to serve as the motivating force for the jet pump I6. A by-pass line 3! is connected from the fuel supply line 22 to the high pressure line I4 to by-pass fuel from the discharge side of the main engine fuel pump 2I to be used as a source of supply for fluid at a high pressure andvelocity to the jet I5. A control valve i3 is provided in the by-pass line `3I to control the passage of fuel under pressure through said by-pass line.
3 be of any well known form such as a. V-belt or a chain and sprocket drive.
The high pressure supply line 22, the by-pass line 3|, and the high pressure line I4 are all diagrammatically shown as being encircled by and spaced inwardly from a coaxial casing 35, the space between the outside of said high pressure line and the inside of said casing forming a low pressure line or passageway 35. Said low pressure passageway is herein shown as being closed at its ends adjacent the pump 2l and engine 23 and as leading through the opening II in the sump I3 in the bottom of the tank I0 to permit or conduct any fuel leaking from a ruptured high pressure line to be returned to the tank ID.
As shown in Figure 2, the casing 35 for the low pressure line 36 is self-sealing, so as to seal itself in the event of damage thereto, as by gun fire, so that a bullet passing through said casing may rupture the casing of the low pressure line but the rupture in the casing of the low pressure line will seal itself and thus prevent the loss of fuel, which may be returned to the tank It! to prevent the building up of pressure in said low pressure line to an undesirable extent.
From the foregoing description it is obvious that fuel at a low pressure is drawn into the throat of the venturi I8 by the motivating force or aspirating effect of the fuel discharged from the jet I5 at a high velocity into the throat I8 of the venturi to boost the fuel pressure at the intake of the main engine pump 2i and thus to assure that the fuel be delivered to the engine under various atmospheric conditions and assuring a constant supply of fuel from the tank I until it has been scavenged substantially dry by said jet booster pump. It will also be seen that a separate pump driven from the aircraft engine is provided to by-pass fuel from the intake side of the main engine fuel pump 2l under a high pressure and velocity to jet I; that fuel may also be by-passed to the high pressure line I4 through the by-pass line 3| contro'lled by the valve 33; and that either or both the high pressure pump 2T or the by-pass line 3| may be used to supply fuel to the jet I5. It may further be seen that all high pressure lines in this system are enclosed and encircled by a self-sealing low pressure line connected to prevent the loss of fuel from the high pressure line upon rupture thereof.
In Figure 3 we show the application of our invention to scavenging lubricating oil from a casing for the lubricated parts of an aircraft engine or transmission. In this form of our invention a casing 40 for transmission gearing, indicated generally by reference character 4I, is shown as having a venturi 42 of a jet pump 43 leading from the bottom thereof and as being connected to a return line 44 leading to an oil storage reservoir 45. An intake line 4S for an oil pump 4l leads from the bottom of said reservoir 45 to the intake side of said pump. A high pressure line 4leads from the pressure or discharge side of said pump to jets 49-49, shown as extending through the top of the casing 40 and directed to supply lubricant under pressure to the gearing 4I. A by-pass line 50 is connected from the high pressure line 48 to a high pressure jet 5I arranged to discharge oil at a high pressure and velocity into the mouth of the venturi 43.
Lubricant at high pressure thus enters the casing 4D through the jets 49-49, and after it has been used, drops to the bottom of said casing where the high pressure jet 5I of the jet pump 43 pumps it back to the tank 45 through the return line 44. rrhis arrangement assures com- .4 plete scavenging of the oil from said casing, returning it for re-use in the lubricating system, and also makes it possible to scavenge oil which may contain large quantities of contaminants, since the oil entering the throat of the venturi 42 under a high pressure and velocity continually passes into said throat and forces the oil thereinto at such a high pressure and velocity that said throat must be completely plugged before the pumping operation will cease.
It will be understood that various modifications and variations may be eected without departing from the spirit and scope of the novel concepts of the present invention.
