Abstract
A heat transmission retardant member which is a cylinder-shaped resin tube made of nylon or polyacetals is mounted between an adsorbent and an inner wall of a hollow portion of a heat-sensing driven member with a space ′ between said inner wall. The hollow portion of said heat-sensing driven member includes said adsorbent said heat transmission retardant member made of resin, and said space ′. Said heat transmission retardant member comprises plural protrusions, and by positioning said protrusions to contact said inner wall, said space ′ is formed. Since said space ′ is formed between said inner wall of the hollow portion of said heat-sensing driven member and said heat transmission retardant member 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.
