Abstract: A stove has a fuel reservoir which communicates via fuel supply line with a burner. A stop valve in the fuel supply line controls fuel supply from the fuel reservoir to the burner. A normally-open emergency shut-off valve in the fuel supply line is operable to close the fuel supply line if the fuel pressure rises a preset amount above a normal operating pressure due to overheating of the fuel reservoir for example.
Abstract: The stove has a fuel reservoir formed by a cylindrical canister. A stop valve is mounted at a top of the canister for regulating supply of fuel gas from the canister through a fuel passage to a burner head mounted on top of the stop valve. The fuel passage has an inlet in the canister and an outlet at the burner head and extends through the stop valve which is mounted in the fuel passage. The stop valve is a rotary valve controlled by a hand wheel which can be rotated by a user to move the stop valve between open and closed positions. An emergency shut-off valve is mounted at the inlet to the fuel passage and is operable when the stove is knocked over.
