（１）を温度に応じてピッチ間隔（Ｉりが変化する材質
で構成したものである。I+) Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a method in which the pitch interval of the fill spring (1) is used as a passage, and the coil spring (1) is made of a material whose pitch interval (I) changes depending on the temperature. It is composed of

すると自由長が変化し、コイルの全長は変化しないので
温度が変化するとピッチ間隔が変化するのである。A shape memory alloy was used as the material of the coil spring (1). For example, shape memory alloys include Ni-Ti thread and O
Although there are two types of U-based shape memory alloys, a 1-based shape memory alloy was used in this example. The free length of this coil spring (1) changes as the temperature changes, but the overall length of the coil does not change, so the pitch interval changes as the temperature changes.
本発明装置を湯沸器の入水流路あるいは出湯流路に介在
させた場合の実施例を図示した。An embodiment in which the device of the present invention is interposed in a water inlet flow path or a hot water outlet flow path of a water heater is illustrated.

て流量を小から大に調節するようにした。In Figures 1 and 2, the fill spring (1) is interposed in the orthogonal flow path (2), one end is fixed and the other end is a free end (3), so that the water entering or exiting temperature changes from low to high temperature. When the change occurs, the pitch interval of the coil spring (1) changes from el to 19, that is, from small to large, as shown in Figs. 1 and 2, thereby increasing the passing area and reducing the flow rate. I adjusted it from to large.
