ABSTRACT:
A heater includes a handle, a combustion chamber, a valve and a thermal controller. A reservoir for fuel can be installed in the handle. The combustion chamber is mounted on the handle. The valve is received in the handle. The valve defines a passage through which fuel can flow from the reservoir into the combustion chamber for combustion. The thermal controller includes a memory element at least partially received in the combustion chamber and a rod connected between the memory element and the valve for controlling a rate at which fuel can flow through the passage defined in the valve based on the temperature in the combustion chamber. The memory element is a helical memory metal element. The memory element shrinks or expands when the temperature increases above a certain value.
