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.
Claims16
A stove, including:
- a burner,
- a fuel reservoir for storing a fuel gas,
- a fuel passage communicating between the fuel reservoir and the burner,
- a stop valve in the fuel passage which is operable to control the supply of fuel gas from the fuel reservoir to the burner,
- a normally open emergency shut-off valve mounted at the fuel passage,
- said emergency shut-off valve being operable to close the fuel passage to stop fuel gas flow through said fuel passage when the stove is tipped away from a normal upstanding operating position by a preset amount,
- wherein the emergency shut-off valve comprises a valve chamber having an inlet for communicating with the fuel reservoir and an outlet for communication with the fuel passage to the burner,
- a valve seat at the outlet, a valve member movable through the valve chamber between a disengaged open position and an engaged closed position in sealing engagement with the valve seat, and
- wherein the emergency shut-off valve is engagable with an inlet of the fuel passage and a pin on the stop valve is engagable through the inlet of the fuel passage when the stop valve is in the closed position to disengage the emergency shut-off valve from the inlet to reset the emergency shut-off valve into an open position.
