Abstract
A liquid fuel campstove is provided with a piezoelectric ignition system. The campstove includes a liquid fuel tank, a burner assembly having a fuel inlet and fuel outlet orifices, a generator tube which is connected to the fuel tank and extends adjacent the burner assembly, and a U-shaped venturi tube which extends from the generator to the fuel inlet of the burner assembly. A pilot tube is inserted into the venturi tube and extends to adjacent the fuel outlet orifices of the burner assembly. The electrode of the piezoelectric ignition system is positioned adjacent the end of the pilot tube.
