LIQUID FUEL BURNER

摘要

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).
