Abstract: A mixing valve mechanism and a thermostat respectively incorporated in a body are housed in a cartridge of an axial cylinder shape, and the cartridge is inserted into the body so as to be freely rotated around a rotary axis in the longitudinal axial direction. An adjustment screw is provided on one end of the body, i.e., on the side opposite to a projected or retracted operating rod of the thermostat in the cartridge so as to be freely displaced in the axial direction of the body to support the operating rod. The adjustment screw and one end of the cartridge and the adjustment screw and the body are respectively connected together through a screw or a spline such that the adjustment screw is displaced in the axial direction of the body through the rotation of the cartridge. The cartridge is connected to a temperature control dial provided on the other end of the body so as to be rotated by the operation of rotating the temperature control dial.

Abstract: The body of an automatic water combination faucet has, as separate parts, an outer cylinder with the cylindrical wall thereof having assembling hole portions for assembling connectors connected to the hot water, water and combination water lines and an inner cylinder housing accommodating a mixing valve unit. The inner cylinder housing is formed by casting or the like, and has, as integral and continuous parts, a main portion accommodating the mixing valve unit, a passage-defining portion in the form of a line for leading hot water to the main portion, and a passage-defining portion in the form of a duct line for leading out combination water. A separate cap which surrounds an adjustment screw unit of the mixing valve unit is engagedly coupled to the main portion.
