  • Housing for multiple mixing valves
    Patent number: 11920691
    Abstract: A valve assembly includes a first mixing valve, a second mixing valve, a housing configured to receive the first mixing valve and the second mixing valve, and a check valve. The housing defines a first fluid inlet, a second fluid inlet, a first fluid passage, and a second fluid passage fluidly coupling the second fluid inlet to the first mixing valve and the second mixing valve. The first fluid passage includes a first fluid inlet chamber fluidly coupled to the first fluid inlet, a first connecting passage fluidly coupling the first fluid inlet chamber to the first mixing valve, and a second connecting passage fluidly coupling the first fluid inlet chamber to the second mixing valve. The check valve is coupled to the housing and configured to substantially prevent fluid from flowing from the first mixing valve to the first fluid inlet chamber.
