Document Type and Number:

WIPO Patent Application WO/2008/069233

Kind Code:

A1

Abstract:

A mixing faucet having a temperature adjustment dial (D) and a tubular casing (1) in which a hot water inlet (a) and a cold water inlet (b) are formed, wherein the mixing faucet further has a control valve body (2) and temperature adjustment means (8, 900). The control valve body (2) receives at one end a load from an urging body (4) and at the other end a load from an actuator (5) and changes the proportion of opening and closing of the hot water inlet (a) and the cold water inlet (b) depending on the balance of the loads that the control valve body receives from the urging body (4) and the actuator (5). Thus, the control valve body (2) adjusts the mixture ratio between hot water incoming from the hot water inlet (a) and cold water incoming from the cold water inlet (b). In the temperature adjustment means (8, 900), its one end is fixed to the temperature adjustment dial (D) and the other end adjusts the position of the control valve body (2) through the urging body (4). A radially expanding tapered skirt section (94) is formed at the temperature adjustment means (8, 900) at its end on the control valve body (2) side.
