Abstract
A fuel injection system having an ultrasonically vibrated nozzle to provide for fuel atomisation. The nozzle has a fuel outlet having a ball valve to give a quick fuel shut-off. Fuel circulates continuously around the ball valve by passing through passageways. The circulating fuel swirls around the ball valve and this swirling facilitates quick fuel atomisation when the nozzle is vibrated.

The invention has applied in all fields of technology requiring injection of fuel and may therefore be used with, for example, turbo-jet engines, turbo-prop engines, other gas turbine engines, internal combustion engines of the two stroke, four stroke and diesel variety and central heating boilers.
It is known that atomization of liquid fuel can be effected by employing fuel injection devices which are vibrated, the vibrations being sufficient to cause the fuel to become atomized. In our co-pending U.S. application Ser. No. 327,905 we have described a vibratory fuel injection device employing a non-return valve,
preferably a ball valve, to prevent loss of fuel from the device when fuel ejection is not desired. The use of the non-return valve enables abrupt fuel cut-off and this is desirable to avoid wasting fuel and to enable good engine cut-off control to be achieved.
We have now found that efficient fuel atomization can be achieved if, during periods when the fuel injection device is not emitting fuel, the fuel is caused to swirl, especially in the vicinity of the non-return valve. The swirling fuel is more easily atomized when the fuel injection device is vibrated than non-swirling fuel. Greater ease of fuel atomization is especially desirable when the fuel injection device is only vibrated for relatively short periods, eg at low engine speeds when relatively little fuel is required.
The present invention thus provides in a broad aspect a fuel injection device comprising a housing having a fuel inlet, a first fuel outlet, a second fuel outlet, a swirl chamber position substantially adjacent said first fuel outlet, a valve for opening and closing said first fuel outlet and which is positioned solely in said swirl chamber and presents a substantial abutment area to the fuel in said swirl chamber, a first fuel passageway leading from said fuel inlet to said swirl chamber, and a second fuel passageway leading from said swirl chamber to said second fuel outlet, said fuel injection device being such that A. when said valve is closed then fuel can pass continuously through said device with fuel swirlage in said swirl chamber by entering said fuel inlet, passing along said first fuel passageway and into said swirl chamber, and then along said second fuel passageway, and then through said second fuel outlet, said fuel swirlage in said swirl chamber being caused by said movement of said fuel from said first fuel passageway to said second fuel passageway and by contact of said fuel with said abutment area of said valve, and 1 B. when said valve is open, fuel can pass throughsaid first fuel outlet in an atomized condition.
Preferably, the valve is a floating ball valve.
The present invention also provides a fuel injection system including a fuel injection device in accordance with the invention. 1
Preferably, the fuel injection system comprises a fuel injection device in accordance with the invention for injecting fuel into adesired area, for example into a duct carrying air to an engine, and a vibrator for vibrating the nozzle to produce atomization of the fuel injected by the nozzle.
Other types of non-return valve in addition to the above mentioned ball valve may of course be employed if desired. Various types of vibrator are known and the vibrator may include a piezo-electric element.
The fuel injection system of the present invention may include a fuel feed device for providing a flow of fuel to the nozzle. The fuel injection system may also include a timing control device which limits the energisation of the nozzlevibrations, e.g. ultrasonic vibrations, to uniformly spaced periods. Each timing period may constitute an adjustable part of the cycle related to the revolution of an engine. The timing control device may be so connected to an engine as to limit energisation of the ultrasonic vibrator to an adjustable part of each suction stroke of each cylinder fed by a flow duct.
In a preferred arrangement, in which there are periods when the fuel injection device is vibrated in its longitudinal direction and in which there are periods when there is no such vibration, the ball valve is arranged to be normally held on its seat by fuel pressure assisted, if desired or necessary, by spring action. Inertia forces are relied upon to effect, during the time in which vibrations are applied to the nozzle, periodic opening of the non-return valve to permit the flow of fuel. If desired, this inertia effect may be assisted or even replaced by magnetic action upon the non'retum valve, for example with the help of a solenoid coil which is energised during thedesired period of fuel injection, i.e. during the periods of vibration of the nozzle. The non-return valve is in this case made wholly or partly of magnetic material and is so arranged as to be urged in a direction away from its seat by the magnetic action of the energised solenoid.
When the fuel injection nozzle is vibrated, it will generally be vibrated with so-called ultrasonic vibrations or at so-called ultrasonic frequency. The vibrations obviously want to be sufficient to cause the jet of liquid to disintegrate into small mist-lilce particles. The frequency range in question may in practice be found to have its lower limit somewhere near the upper limit of audibility to a human ear. However, for reasons of noise suppression, it is generally preferable in practice to use frequencies high enough to ensure that audible sound is not produced.
An embodiment of the invention will now be described by way of example and with reference to the accompanying drawing which shows one form of fuel injection device in accordance with the invention.
Referring to the drawing, there is shown a fuel injection device 2having a housing 4. The housing 4 is provided with a fuel inlet 6, a first fuel outlet 8 and a second fuel outlet 10. A ball valve 12 is positioned at the inlet side of the first fuel outlet 8 and it will be noticed that the outlet 8 is provided with a restricted orifice 16 which is defined by an internal shoulder 18. Leading towards the ball valve 12 is an annular fuel passageway 20and leading away from the ballvalve 12 is an internal fuel passageway 22.
In operation of the device 2, fuel enters the device 2 through the fuel inlet 6 and passes up through the passageway 20 where it enters a swirl chamber 24 adjacent the ball valve 12. In this chamber 24, the fuel swirls around the ball valve 12, whenthe ball valve is in the closed position shown in the drawing, and then ultimately passes downwards along the fuel passageway 22. The fuel can then leave the device 2 through the second fuel outlet 10. When it is desired to eject fuel through the first outlet 8, the nozzle is vibrated by means of an ultrasonic vibrator 36. The vibrator vibrates the nozzle quickly and the ball valve is moved very many times away from its seat against the shoulder 18. Because of the swirling of the fuel, acceptable fuel atomization occurs immediately or alternatively very soon after the vibration is started.
The device 2 shown in the darwing can be constructed of any desired material. The passageway 20 will normally be constructed by drilling a centre bore 26 into the housing 4 and subsequently locating in the bore 26 a pipe 22A defining the bore 22. The pipe 22A is located by means of brazing joints 30, 32. It will be noted that the brazing joint 32 is provided with passageways 34 to allow fuel to pass therethrough. The brazing joint 30 is not provided with passageways because it is not desired to allow the fuel in the passageway 20 to pass downwardly to the second outlet 10. The fuel in the passageway 20 has to pass upwards through the passageways 34 in the brazing joint 32 and the fuel in the pipe 22A has to pass downwardly through the passageway 22 and therefore through the centre of the brazing joint 30. It will thus be apparent that when the device 2 is not being vibrated to eject fuel, then fuel is passing continuously through the device 2 from the inlet 6 to the outlet 10. Fuel leaving the outlet 10 can be recirculated, e.g. via a fuel tank.
