PURPOSE:To increase the opening-degree of an annular opened edge when a bimetal senses the temperature variation, by making the bimetal into U-figure shape. CONSTITUTION:Fluid flows from an inflow port 1 and further flows into a sealed chamber 4 from an injection hole 5, and flows to an effluence port 2 from a discharge hole 6. When the temperature of the fluid rises, an annular metal 8 opens an opened port part 12 in accordance with the heating amount. When the opened port part 12 is opened, the top edge part 11 of a closing-element holding body 10 lowers according to the degree of opening, and the discharge hole 6 is closed by the top edge 17 of a closing element 15. |
