Abstract
The invention provides a liquid fuel burner (110) comprising a burner head (114), a liquid fuel reservoir (116) for containing a liquid fuel, and a pump (118) for pumping the liquid fuel from the reservoir (116) to the burner head (114). The pump (118) includes a cylinder (140), and a piston (142) which is displaceable relative to the cylinder (140) so that liquid fuel is drawn into the cylinder (140) when the piston and cylinder are displaced in a first direction relative to one another, and the liquid fuel is pumped out of the cylinder (140) when the piston and cylinder are displaced in a second, opposite direction relative to one another. The pump (118) also includes an inlet valve (144) for allowing liquid fuel to be drawn into the cylinder (140) from the reservoir (116), an outlet valve (146) for allowing liquid fuel to be pumped out of the cylinder (140) to the burner head (114), and a displaceable mass which due to its weight applies sufficient force to cause displacement of the piston (142) relative to the cylinder (140) in the second direction, thereby to pump liquid fuel out of the cylinder (140) to the burner head (114).
Claims
1. A liquid fuel burner comprising: a burner head; a liquid fuel reservoir for containing a liquid fuel; and a pump for pumping the liquid fuel from the reservoir to the burner head under pressure, the pump including: a cylinder; a piston which is displaceable relative to the cylinder so that liquid fuel is drawn into the cylinder when the piston and cylinder are displaced in a first direction relative to one another, and the liquid fuel is pumped out of the cylinder when the piston and cylinder are displaced in a second, opposite direction relative to one another; a one-way inlet valve for allowing liquid fuel to be drawn into the cylinder from the reservoir; a one-way outlet valve for allowing liquid fuel to be pumped out of the cylinder to the burner head; a displaceable mass which due to its weight applies sufficient force to cause displacement of the piston relative to the cylinder in the second direction, thereby to pump liquid fuel out of the cylinder to the burner head under pressure; and a control mechanism for applying a variable resistance to the displacement of the piston relative to the cylinder, thereby to allow for the adjustment of the supply of pressured liquid fuel to the burner head.
2. A liquid fuel burner according to claim 1 , wherein the piston is displaceable within the cylinder towards a raised condition for drawing liquid fuel into the cylinder and towards a lowered condition for pumping liquid fuel out of the cylinder.
3. A liquid fuel burner according to claim 2, wherein the piston is attached to the burner head via a piston tube, and the piston defines an opening for allowing fluid communication between the cylinder and the piston tube.
4. A liquid fuel burner according to claim 3, wherein the control mechanism includes an adjustment screw for applying a variable resistance to the displacement of the piston tube.
5. A liquid fuel burner according to claim 4, wherein the piston tube is arranged to pass through a bush, and the adjustment screw is threaded into the bush so as to be eπgagable with the piston tube.
6. A liquid fuel burner according to any one of the preceding claims, wherein the cylinder is located within the liquid fuel reservoir.
7. A liquid fuel burner according to claim 6, wherein the cylinder communicates with the reservoir via the inlet valve and a filter.
8. A liquid fuel burner according to any one of the preceding claims, wherein the inlet valve and the outlet valve each include a valve closure which, in ordinary operation, is movable relative to a valve seat between an open position in which the valve closure is spaced from the valve seat to allow for one-way flow of liquid fuel through the valve, and a closed position in which the valve closure engages the valve seat to prevent liquid fuel flow through the valve.
9. A liquid fuel burner according to claim 8, wherein, for each valve, the valve closure is displaceable relative to the valve seat when the liquid fuel burner is tipped to allow liquid fuel to flow through the valve in a direction opposite to the one-way, ordinary operation flow of liquid fuel.
10. A liquid fuel burner according to claim 1, wherein the piston is fixed relative to a frame of the burner and the cylinder is displaceable relative to the burner frame.
11. A liquid fuel burner according to claim 10, wherein the displaceable mass forms part of, or is attached to, the cylinder, and the piston includes ports for allowing the liquid fuel to be drawn into the cylinder or pumped out of the cylinder,
12. A liquid fuel burner according to either claim 10 or claim 11 , wherein the burner includes a frame formed from tubular sections, and the reservoir is formed by at least a portion of the tubular sections.
13. A liquid fuel burner according to claim 12, wherein the frame is curved along side portions thereof and the burner includes a stabilising mass for self-righting the frame if the burner is tipped to one side.
14. A liquid fuel burner according to claim 13, wherein the stabilising mass is the displaceable mass.
15. A liquid fuel burner according to any one of claims 10 to 14, wherein the control mechanism comprises a valve for controlling the delivery of liquid fuel to the burner head and hence the intensity of combustion at the burner head.
16. A liquid fuel burner according to any one of the preceding claims, wherein the burner includes a duel shut-off device for preventing the flow of liquid fuel to the burner head when the pressure at the burner head drops below a predetermined magnitude, and for preventing back-pressure displacement of the liquid fuel from the burner head to the cylinder when the pressure at the burner head rises above a predetermined magnitude".
17. A pump for pumping liquid fuel from a reservoir to a burner head of a liquid fuel burner, the pump including: a cylinder; a piston which is displaceable relative to the cylinder so that liquid fuel is drawn into the cylinder when the piston and cylinder are displaced in a first direction relative to one another, and the liquid fuel is pumped out of the cylinder when the piston and cylinder are displaced in a second, opposite direction relative to one another; a one-way inlet valve for allowing liquid fuel to be drawn into the cylinder from the reservoir; a one-way outlet valve for allowing liquid fuel to be pumped out of the cylinder to the burner head; a displaceable mass which due to its weight applies sufficient force to cause displacement of the piston relative to the cylinder in the second direction, thereby to pump liquid fuel out of the cylinder to the burner head under pressure; and a control mechanism for applying a variable resistance to the displacement of the piston relative to the cylinder, thereby to allow for the adjustment of the supply of pressured liquid fuel to the burner head.
