Claims

[Claims for Utility Model Registration] (1) Fluid inlet 9 and outlet 10, and first and second channels R that are branched from each other and communicate and connect the inlet 9 and the outlet 10, respectively. ₁ and _R2 ; a thermally responsive member 12 that is attached to the outside of the valve box 8 and displaces in a specific direction as it expands and contracts in response to changes in ambient temperature; a valve stem 15 provided in the valve box 8 so as to be slidable in a direction intersecting each of the first and second flow paths R ₁ and R ₂ in conjunction with the response member 12; and the first flow path R _{1 .} a first valve element 21 which is disposed in the valve body 21 and is engaged with the valve stem 15 and is displaced from the fully closed state to the open side as the thermally responsive member 12 is displaced during expansion; and the second flow path R2 _. The first valve body 21 is provided in
a second valve body 22 that is latched to the valve stem 15 and displaced from the fully closed state to the open side without being displaced; and a second valve body 22 that is displaced from the fully closed state to the open side; A flow rate regulating valve consisting of a bullet 23 that biases the flow rate. (2) The valve stem 15 and the first and second valve bodies 2
1 and 22, respectively, the first and second
The flow rate regulating valve according to claim 1, which is provided with the flexibility to displace only the valve stem 15 within a set range without displacing either of the valve bodies 21 and 22.
