Abstract
A device is provided to prevent the autorotation of the temperature adjustment handle in an automatic hot and cold water mixing valve. A member is prevented from moving in the circumferential direction of the body and is pressed in the radial direction by a spring against the periphery of an adjusting screw receiver, which forms the rotation shaft of the temperature adjustment handle incorporated in the body. Alternatively, the member is dressed against a connecting sleeve connected to the adjusting screw receiver and the temperature adjustment handle. The member is pressed with sufficient force to oppose autorotation in the temperature adjusting handle when the temperature is set.
