inventionrelates to means for controlling the supply of liquid fuel from a rotary pump to a jet-engine or gasturbine.
The object of the invention is to obviate excessive supply of fuel during, acceleration.
The invention comprises the combination of a throttle for controllingv the rate of flow of fuel in a fuel-supply pipe between the pump and burner, liquid-actuated means for actuating the throttle, a control valve responsive to fuel pressure for controlling the throttle-actuating means, and a governor for controlling the liquid acting on the throttle-actuating means.
In the accompanying drawings:
Figures 14 represent diagrammatically four typical embodiments of the invention.
Referring to Figure 1, there is arranged in a main fuel-supply pipe a. between a centrifugal pump b (adapted to be driven by the engine) and a burner c, an axially slidable throttle d for controlling the rate of supply of fuel from the pump to the burner, the throttle being of the kind comprising a conical or like plug co-operating with an orifice e in a hollow body part f. The throttleactuating means comprises a piston g formed on or secured to one end of the throttle, the piston being slidable in a cylindrical chamber h in the said part f and being loaded by a spring'iwhich tends to move the throttle to its fully open position, The end of the chamber it remote from that through which the throttle extends is connected. by a branch passage 1' to the main fuel supply pipe at the inlet side of the throttle. Also there is combined'with the said means a stop k for restricting the extent to which the throttle can be moved towards its closed position under the action of fuel pressure. This stop extends from a piston m loaded by a spring n and slidable in a cylindrical chamber which at one end is connected by a passage p to the said passage j, so that the stop can'be retracted by fuel pressure in opposition to the spring when a predetermined fuel pressure is reached.
The end of the cylindrical chamber h remote from the passage j is connected by a passage q to a control valve. This latter comprises a hollow body part r which is divided into two compartments by a diaphragm s (or piston) which carries a closure member I co-operating with a seating 11 at the entrance to the said pipe, the closure member being held on its seating by a spring v. The said compartments are respectively connected by passages w, x, to the inlet and outlet sides of the pump, so that when the fuel pressure in passage x reaches a predetermined amount it can open the valve.
Also in the said passage q between the control valve and the throttle actuating means there is arranged any suitable governing means for controlling the pressure of the fuel supplied through the said passage to the throttleactuating means, the said governing means being responsive to the speed of the pump in the system.
The particular form of governing means shown in Figure 1, comprises a hollow body part 2 in which is formed 2,769,488 Patented Nov. 1.956
a chamber 3 enclosing'a gap in the passage q, and adjacent to this gap is arranged a transversely'movab'le shutter 4' which can obstruct the flow of liquid across the gap from one part' of the passage q to the other. The shutter is operable by a diaphragm 5' which divides another chamber in the part 2 into two compartments one of which contains a spring 6' acting on the diaphragm. The other compartmentis connected by a passage 7 to the fuel pipe a, or to any other source of liquid under pressure related to the speed of the engine. Excess liquid from the chamber 3 is returned to the pump by way of a passage 8.
The action of the governor is such that when theshutter is retracted full pressure is exerted on the left hand side of the throttle-actuating piston g. In this condition both sides of the said piston are subject to substantially equal liquid pressures and the piston is moved by the spring 1' to the position in which the throttle a is fully open. When the shutter 4 is moved into the gap in the passage q, the liquid pressure acting on the left hand side of the piston g is reduced, and the preponderating liquid pressure then acting on the right handside moves the throttle d against the action of the spring i for reducing the supply of liquid fuel to the burner.
The mode of action of the system shown in Figure 1 is as follows: On starting the pump b the throttle. d is" fully open, but when a certain fuel pressure is attained this moves the throttle into contact with the stop k for restricting the rate of supply of fuel to the burner, so obviating risk of over-fuelling while the speed isincreasing. Later, and, when the fuel. pressure reaches a higher amount, the control valve t opens. and admits fuel to the left hand end of the cylinder h of the throttleactuating means. so enabling the throttle to be retracted by the associated spring for increasing the rate of fuel supply to the burner. When the fuel pressure reaches its normal working amount, it retracts the stop k, and there after the position of the throttle is determined by the governing means acting on the fuel supplied. through the valve t' to the throttle-actuating means.
In the embodiment of the invention shown'in Figure 2, the throttle d consists ofa piston-type valve, having a reduced and suitably shaped part 9' for controlling: the rate of flow of fuel through the orifice e. At one end the throttle is connected to actuating means as above described (excepting that the stop is omitted). The other end can enter a cylindrical chamber 10 the end 11 of which is closed by a valve 12. This valve is carried by a diaphragm 1'3 loaded by a spring 14. The diaphragm divides a chamber 15 into two compartments, one of which is connected by a passage 16 to the inlet side of the pump, the other being connected by a passage 17 to the pipe q of the throttle controlling means. When the left hand end of the throttle d enters the chamber 10 the fuel thereby entrapped in the said chamber serves as a stop, so long as the valve 12 remains closed.
The mode of action of the system shown in Figure 2 is essentially similar to that of the system shown in Figure 1. On starting the pump, the fuel pressure acting on the right hand side of the piston g moves the throttle to its restricted position, the extent of this movement being limited by the liquid entrapped in the chamber 10. With increase of the fuel pressure the control valve t is opened, and also the valve 12. Thereafter the rate of flow of fuel to the burner is controlled by movement of the throttle d in response to the control of the governing means.
In the embodiment of the invention shown in Figure 3, the throttle d is of a similar form to that shown in Figure 1 (excepting that the stop is omitted) and in parallel with the throttle is arranged a by-pass device 20 which contains a normally open valve 21. The valve is operable by fuel pressure acting on a piston 22 loaded by a spring 23'which'is' stronger than the spring 1', the piston being contained in a cylindrical chamber which at its ends is connected by passages 24-,25 ,to the fuel pipe va and the pump inlet respectively. e I "The arrangement is such that during the starting condition the throttle is fully closed by the fuel pressure, and the 'by-pass valve 21 is fully open. The rate of supply of liquid fuel to the burner is, in this condition, determined by the by-pass valve. With increased fuel pressure the by-pass valve is closed, and the control valve is opened, the rate of fuel supply being then determined by the throttle in response to the action of the governor.
In other respects the arrangement shown in Figure 3 is essentially similar to that shown in Figure l, excepting that the spring i acting on the piston g is weaker than that of the Figure l arrangement and allows the throttle to be closed under relatively low fuel pressure.
The embodiment of the invention shown in Figure 4 I vditfers from that of Figure 1, mainly in that a different governor and control valves are provided and the two endsofthe cylinderh of the throttle-actuating means are interconnected by an additional passage 39 containing a restricted orifice 40. In this arrangement the governor comprises a hollow body part 27 which includes two chambers. One of the chambers contains a valve seating 28 in communication by way of a passage 29 with the seating of .the control valve 2. The other chamber is divided into two'compartments by a diaphragm 30 which acts on one end of a lever 31 having parts in both chambers. The .other end of thelever carries a valve 32 and is loaded by a spring 33,the valve 32 being normally losed, and the lever being operable by fuel pressure acting onvone side of the diaphragm. U
i The control valve t is normally open and is carried by a' diaphragm s loaded by a spring v, the side of the V diaphragm remote from the spring and valve being subject to liquid fuel pressure;
I Themode of action is as follows:
When starting the throttle d is movedby fuel pressure to therestricted position determined by the stop k. When the fuel pressure reaches a predetermined amount a the control valve t is closed and the'consequent balancing of the fuel, pressures acting on the piston by way 'of the passage 39, enables the spring i to move the throttle to its fully open position. Thereafter the rate of flow of fuel to the burner is controlled by movement of the throttle in response to the action of the governor which, with opening ofthe' valve 32, enables the fuel pressure acting on the piston'g tosvary the position of the throttle.
Having thus described our invention what we claim as new and desire to secure by Letters Patent is: '1. A liquid fuel supply system comprising in combination a centrifugal pump having an inlet and an outlet for liquid fuel, a fuel delivery pipe communicating with said outlet, at spring-loaded throttle arranged to provide a'variable fuel-flow restriction insaidpipe, a
