摘要： An expansion valve has a housing with a hole extending through its outer wall. A plug body seals the hole after a heat sensing gas, which senses the temperature of the gas-phase refrigerant passing through the expansion valve, is pressurized in the housing through the hole. The plug body, which is made from a cut metallic material, seals the hole to maintain the pressurized gas in the housing. The plug body is welded to the housing by an electrical weld. A corrosion inhibitor can be applied around the weld periphery to prevent corrosion from forming at the weld areas. The plug body has a line contact portion formed by a tapered surface, e.g., a conical portion, with a plurality of concentrically arranged a line contact portion, which has spaced projections. These projections can be formed, for instance, by cutting circumferentially around the tapered surface. The spacings between the spaced projections form a plurality of weld areas that can securely seal the plug body at the line contact portion to the housing.

By the existence of the activated carbon 70, the hunting phenomenon and the invasion of the refrigerant to a lower chamber 85 is prevented, and the heat from the heat transmission retardant member 140 is transmitted to the heat sensing driven member 100 via space 144 which enables to provide a further retardation to the response of the valve to the temperature change of the refrigant exiting the evaporator. The hunting is further suppressed effectively.

摘要： 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.

摘要： A heat transmission retardant member 140 which is a cylinder-shaped resin tube made of nylon or polyacetals is mounted between an adsorbent 40 and an inner wall of a hollow portion of a heat-sensing driven member 100 with a space 140′ between said inner wall. The hollow portion of said heat-sensing driven member 100 includes said adsorbent 40, said heat transmission retardant member 140 made of resin, and said space 140′. Said heat transmission retardant member 140 comprises plural protrusions, and by positioning said protrusions to contact said inner wall, said space 140′ is formed. Since said space 140′ is formed between said inner wall of the hollow portion of said heat-sensing driven member 100 and said heat transmission retardant member 140, not only is the heat transmission to the granular activated carbon delayed by the heat transmission retardant member, but said space also effectively delays the transmission of the temperature variation of the refrigerant to the heat transmission retardant member. Thus, hunting of the valve is even further effectively suppressed.
