<p><P>PROBLEM TO BE SOLVED: To shut off a distance between a hot water valve 3a and a hot water valve seat (a) completely when spouting water without enlarging a temperature sensitive spring 5 composed of a SMA spring. <P>SOLUTION: In this hot water and water combination plug constituted by holding a control valve element 3 at a balanced position of two springs including a bias spring 4 and the temperature sensing spring 5 and moving an adjusting screw 6a for supporting the bias spring 4 in the axial direction to change and set a support position of the bias spring 4 and set temperature, a terminal side of the bias spring 4 is supported on a supporting member (g) formed separately from the adjusting screw 6a, the supporting member (g) is slidably fitted and inserted into a through hole 63 provided in the adjusting screw 6a and is linked to the adjusting screw 6a so as to come into mutual contact or separate from each other freely by an abutting part t1 provided in a section protruding onto a bias spring 4 side from the transparent hole 63. A pulling-up spring 7 for energizing the supporting member (g) onto a side for pulling it back to the opposite side to the bias spring 4 for the adjusting screw 6a is provided between a section protruding on the opposite side to the bias spring 4 from the transparent hole 63 and the adjusting screw 6a. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
