ABSTRACT:
A fixing method and assembly of a temperature responsive element capable of detecting variation in temperature of discharge cooling medium of a compressor exactly and rapidly and preventing the compressor from being burned. A through hole is formed in a cover 6 which covers a path 7B for discharge cooling medium of the compressor. A plug 9 is fixed to the through hole from the side of the path by a fixing member 13. In this case, it is sealed airtightly by means of a packing. Lead terminal pins penetrating the plug 9 is insulatively fixed in the plug airtightly. Leads are connected to one ends of the lead terminal pins projecting outside and the temperature responsive clement 8 is connected to the other ends of the lead terminal pins projecting on the side of the discharge path. The temperature responsive clement 8 is disposed not to come into direct contact with a vessel and the cover 6 of the compressor and is exposed to discharge cooling medium as a whole. Consequently, the temperature responsive element can detect a temperature of the discharge cooling medium exactly and rapidly without influence of external disturbance such as heat from the outside and a path 7A for suction cooling medium.
