PURPOSE:To restrain variations in temperature of discharge water, by providing, in a mixed water passage, a reservoir chamber having. CONSTITUTION:The inside of the valve body 5 of a thermostat mixing valve 1 is divided into three passages, a hot water passage 6 communicated with a hot- water supply, a water passage 7 communicated with a water supply and a mixed water passage 8 communicated with both passages 6, 7 and as well with a communicating pipe 3. The mixed water passage is once enlarged within a reservoir chamber 50 and is reduced, gradually toward a downstream side hose 37. The volume of the mixed water in the reservoir chamber 50 is stayed by a predetermined time in order to mix mixed water in a high temperature area based upon variations in the pressure of water supply, again with mixed water in the set temperature area, thereby the amount of overshoot may be restrained, an inside volume in which mixed water may stay. |
