ABSTRACT:
To provide a thermo-element having a simple structure, an improved durability and a good response characteristic, by improving heat conduction of wax and by improving a diaphragm. The wax is blended with small pieces of metal, and a low-melting point alloy having a melting point equal to or higher than a melting point of the wax, which are melted and mixed together in the wax, so as to improve the heat conduction and thus response characteristic of the wax. A thick sealing member comprises a piston insertion bore formed in a central portion thereof, a thick portion between the piston insertion bore and a sealing portion in an outer peripheral region the thick portion being easily deformable. The thick sealing member operates both as a diaphragm and as a gummy fluid in a prior art thermo-element. A thermo-element has a small number of components, a simple structure.
