Abstract
There is disclosed a mixing valve for control of water temperature and pressure from two distinct hot and cold water sources. A pressure equalizing cartridge utilizes radial discharge openings and by axial movement of this cartridge, control of temperature is achieved. By rotary movement of the cartridge, discharge ports in a liner pipe which surrounds the equalizing cartridge are blocked to control the quantity of water discharged.
