Abstract

A gas-powered heating apparatus includes a reservoir for storing fuel, a combustor communicated with the reservoir for burning the fuel, a switch provided between the reservoir and the combustor for turning on/off the supply of the fuel to the combustor from the reservoir and a controlling device provided between the reservoir and the combustor for controlling the rate of the supply of the fuel to the combustor.

Claims

1. A gas-powered heating apparatus comprising a reservoir for storing fuel, a combustor communicated with the reservoir for burning the fuel, a switch provided between the reservoir and the combustor for turning on/off the supply of the fuel to the combustor from the reservoir and a controlling device provided between the reservoir and the combustor for controlling the rate of the supply of the fuel to the combustor.

2. The gas-powered heating apparatus according to claim 1 wherein the controlling device is provided between the switch and the combustor for controlling the rate of the supply of the fuel to the combustor from the switch.

3. The gas-powered heating apparatus according to claim 1 wherein the controlling device controls the rate of the supply of the fuel to the combustor based on the temperature.

4. The gas-powered heating apparatus according to claim 3 wherein the controlling device comprises:

a drum defining an inlet, a first space communicated with the inlet, a second space communicated with the first space, a shoulder formed between the first and second spaces and an outlet communicated with the second space; and

an adjusting element movable towards the shoulder in the second space when the temperature increases.

5. The gas-powered heating apparatus according to claim 4 wherein the adjusting element is a laminate consisting of two metal layers with different thermal expansion coefficients so that it deforms as the temperature changes.

6. The gas-powered heating apparatus according to claim 4 wherein the depth of the second space is larger than the thickness of the adjusting element in order to allow the adjusting element to leave the shoulder so as to allow the fuel to flow to the outlet from the inlet through the first and second spaces.

7. The gas-powered heating apparatus according to claim 4 comprising a cover for sealing the second space.

8. The gas-powered heating apparatus according to claim 3 wherein the controlling device comprises:

a drum defining an inlet and a tapered outlet communicated with the inlet; and

a tapered plug movable in the tapered outlet.

9. The gas-powered heating apparatus according to claim 8 wherein the drum defines a space between the inlet and the tapered outlet, wherein the controlling device comprises an adjusting element put in the space and connected with the tapered plug so that the adjusting element expands and pushes the tapered plug further into the tapered outlet as the temperature rises.

10. The gas-powered heating apparatus according to claim 3 wherein the controlling device comprises:

a drum defining an inlet, a first space communicated with the inlet and an outlet communicated with the second space; and

an adjusting element movable towards the outlet when the temperature increases.

11. The gas-powered heating apparatus according to claim 10 wherein the adjusting element is shaped like a rod.

12. The gas-powered heating apparatus according to claim 11 wherein the adjusting element comprises a fixed end secured to the wall of the space and a free end movable towards the outlet when the temperature rises.
