Abstract

PURPOSE:To reduce the number of component parts to miniaturize a flow adjusting device, by using spaces between the pitches of a coil spring as passages, and by forming the coil spring with materials such that the pitches of the coil spring varies in accordance with temperatures. CONSTITUTION:A coil spring 1 is disposed in orthogonal passages 2 with one end thereof being secured while the other end being served as a free end 3, and arragement is made such that when the temperature of inlet water or outlet hot water varies from a low temperature to a high temperature, the pitches of the coil spring 1 changes from l1 to l2 or increases. That is, the passage area is increased to adjust the flow rate of water, and therefore, the number of component parts may be made less than that of a conventional device composed of a valve coupled with a temperature sensing section, thereby it is possible to miniaturize the flow adjusting device.

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.

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.
