ABSTRACT:
An oil burning lamp has a fuel reservoir, a fuel expansion chamber releasably and sealingly coupled to the fuel reservoir, a burner assembly coupled to the fuel expansion chamber, and an adjustable wick. If the fuel in the fuel reservoir undergoes thermal expansion, it flows into the fuel expansion chamber, thereby preventing fuel leaks and spills. In the preferred embodiment, the burner assembly is permanently coupled to the fuel expansion chamber, thereby preventing users from refueling the lamp while the lamp is burning. The fuel expansion chamber also serves as an overflow fuel chamber, so that if the lamp is inadvertently knocked over, the fuel will flow into the fuel expansion chamber, not out of the lamp.
