Abstract
A heat transmission retardant member is formed of a cup-like shaped resin material utilizing nylon or polyacetals, comprising a collar formed to the outside of the upper end thereof, and a thick-walled cylinder portion having at the lower end thereof a tapered portion . Said retardant member is positioned so that the upper end contacts a support member ′, said collar is supported by the inner surface of a housing , the outer surface of said cylinder portion contacts the inner surface of said housing , and the end of said tapered portion is inserted to a second hole and contacting the outer surface of a heat-sensing driven member and further positioned within a lower chamber defined by a diaphragm . Said retardant member is mounted to said driven member so as to cover the outer surface thereof and being mounted outside the second refrigerant passage , said tapered portion defining a space between the exterior of the driven member and the interior of said cylinder portion . Not only is the hunting phenomenon suppressed by the existence of the activated carbon, but the invasion of the refrigerant to the lower chamber is prevented, and the heat from the heat transmission retardant member is transmitted to the heat-sensing driven member via space which enables to provide a further retardation to the response of the valve to the temperature change of the refrigerant exiting the evaporator. The hunting is further suppressed effectively.
