a flow path 13 which connects these main ports 11, 12, a valve seat 14
which is provided inside the flow path 13, a valve member 17 which
opens/closes the valve seat 14, and a rod 18 which is coupled to the valve
member 17, a cylindrical heat transfer body 28 is disposed at a fixed
position therein so as to surround the rod 18, and the heat transfer body
28 is caused to house a first heater 31 therein, so that a poppet valve is
