<p>Reference 100' refers to a heat-sensing driven member constituting a thermal expansion valve formed by a stainless steel material and the like and having in the inside thereof an adsorbent 40, with a collar 100'a formed to the outside of the opening 100'b of the heat-sensing driven material 100'. A protrusion 100'c and a groove 100'd is formed to said collar 100'a in the downward direction of the drawing. Said protrusion 100'c and said groove 100'd are formed to the whole perimeter of said collar 100'a. Moreover, a diaphragm 82a formed for example of stainless steel material is inserted to said heat-sensing driven member 100' through an opening 82b formed to the center area thereof until it contacts said protrusion 100'c, and said diaphragm 82a is fixed to said heat-sensing driven member 100'. As a result, the diaphragm 82a is welded by said protrusion 100'c between said collar 100'a and said support member 82'a. The end of the diaphragm 82a is sandwiched between housings 81 and 91 and fixed to position by welding. <IMAGE></p> |
