The SMA temperature-sensing spring (5) closes the gap between the hot water valve (3a) and the valve foundation (a) without enlarging the spigot. The control valve (3) is balanced at the equilibrium position between the pre-compressed spring (4) and temperature-sensing spring (5). The desired output-water temperature is set through the adjusting screw (6a) by adjusting the compression force of the adjusting screw (6a) on the pre-compressed spring (4). The pre-compressed spring (4) is supported by the supporting element g which goes through a through hole (63) on the adjusting screw (6a). The part t1 is assembled to the supporting element g at place in between of and to separate the adjusting screw (6a) and the pre-compressed spring (4). The pull spring (7), between the supporting element g and the adjusting screw (6a), is used to pull the supporting element g back to the side which is away from the pre-compressed spring (4).
