Combination faucet device

A combination faucet device comprising:

• a cylindrical mixing chamber connected to both a water port for supplying high-temperature water therethrough and a cold water port from supplying low-temperature water therethrough;
• a movable valve member for controlling at least one of a flow of said high-temperature water supplied through said hot water port and a flow of said low-temperature water supplied through said cold water port so as to adjust a mixing ratio of said high-temperature water to said low-temperature water;
• a temperature sensitive spring having a first end and a second end, said temperature sensitive spring being exposed to a water mixture of said high-temperature water and said low-temperature water mixed in said mixing chamber, said temperature sensitive spring having a spring constant that varies as a function of a temperature of said water mixture, wherein said temperature sensitive spring presses upon and thereby actuates said movable valve member in a first direction;
• a bias spring arranged to press said movable valve member in a second direction opposite to said first direction;
• a pre-load adjusting mechanism for adjusting a pre-load applied onto said bias spring;
• and
• a casing member having a wall for defining said mixing chamber and a valve chamber for accommodating said movable valve member, said temperature sensitive spring, and said bias spring therein, said casing member being disengageably attached to a member having said cold water port or said hot water port formed thereon.

• a movable valve member for controlling at least one of a flow of said high-temperature water supplied through said hot water port and a flow of said low-temperature water supplied through said cold water port, said valve member being operable to adjust a mixing ratio of said high-temperature water to said low-temperature water;
• a temperature sensitive spring exposed to a water mixture of said high-temperature water and said low-temperature water, said temperature sensitive spring having a spring constant that varies as a function of a temperature of said water mixture;
• driving means for actuating said movable valve member in a first direction with a driving force proportional to a pressing force of said temperature sensitive spring;
• a bias spring arranged for pressing said movable valve member in a second direction opposite to said first direction;
• a pre-load adjusting mechanism for adjusting a pre-load applied onto said bias spring;
• a cylindrical flow-path member disposed inside said temperature sensitive spring for defining, together with an inner wall of said mixing chamber, a spring flow path chamber which receives said temperature sensitive spring therein;
• and
• a spring chamber conduit for leading a flow of said water mixture into said spring flow path chamber.
