After that, the water flows pass through a number of outlet holes on a small opening portion of the water mixer towards an outlet passage of the valve. The center of the temperature control sheet is connected to a first end of a transmission shaft.

Abstract: A cartridge of a water supply valve that controls the flow rate and temperature of water without causing interference between flow rate control operation and temperature control operation of the valve. In the cartridge, a flow rate control knob (12) angularly moves forwards and rearwards and actuates a control lever (14) to open or close cold and hot water supply holes (1a and 1b). A temperature control knob (13) is coupled to the flow rate control knob (12), linearly moves leftwards and rightwards, and actuates the control lever (14) to control the opening ratios of the water supply holes. Thus, this cartridge does not change the existing temperature of water during flow rate control operation or change the existing flow rate of water during temperature control operation. This invention reduces the quantity of water to be unnecessarily wasted and, at the same time, prevents undesirable consumption of excessive energy.
