HOT AND COLD WATER MIXING VALVE
The present invention describes a hot and cold water mixing valve, comprising: a temperature adjusting dial (D) which is subjected to temperature control operation, and a main body member having a control valve mechanism (A) for adjusting temperatures of mixed water by operating said temperature adjusting dial (D) and a casing (1) in which a hot water inlet (a) and a cold water inlet (b) are formed and said control valve mechanism (A) is accommodated, and said main body member further comprising: a biasing member (4) made of a material having a fixed spring constant, a temperature sensitive spring (5) which expands or shrinks according to a temperature change, and a control valve member (2) in which a first spring bracket (72) for supporting said biasing member (4) is abutted against one end, and a second spring bracket (70) for supporting said temperature sensitive spring (5) is abutted against the other end, and an opening/closing ratio between said hot water inlet (a) and said cold water inlet (b) is changed by balancing between the loads applied by said biasing member (4) and said temperature sensitive spring (5), to adjust a mixture ratio between the hot water which flows in through said hot water inlet (a) and the cold water which flows in through said cold water inlet (b), characterized in that a mixing chamber (13) for mixing the cold water from said cold water inlet (a) and the hot water from said hot water inlet (b) is provided inside said casing (1), and a third spring bracket (71) for supporting said temperature sensitive spring (5) is formed in said mixing chamber (13), said temperature sensitive spring (5) is constituted by a coil-like large diameter coil spring (5a) wound to have a large diameter and a coil-like small diameter coil spring (5b) wound to have a small diameter, and said large diameter coil spring (5a) and said small diameter coil spring (5b) are arranged so that their axes are coaxial or in parallel, and supported between said second spring bracket (70) and third spring bracket (71), and a cylindrical cover (7) surrounding a perimeter side of said small diameter coil spring (5b) is formed integrally or substantially integrally with said second spring bracket (70) or the third spring bracket (71), the perimeter side of said small diameter coil spring(5b) is enclosed with the cover(7) on an inner circumference side of said large diameter coil spring (5a), and a response of expansion/shrink operation according to the temperature change of said large diameter coil spring (5a) and a response of expansion/shrink operation according to the temperature change of said small diameter coil spring (5b) are differentiated.
