Abstract:
1. A venturi mixing valve assembly, comprising: an open-ended first tubular section adapted to be coupled to a supply of a first gas and a supply of a second gas, said first tubular section having a sleeve defined therein wherein an annular channel open on one end thereof is defined between said sleeve and an inner surface of said first tubular section; an open-ended second tubular section defining an annular region with a plurality of holes and a venturi region coupled to said annular region, said annular region circumscribing at least a portion of said sleeve of said first tubular section and sealed to said sleeve; and an open-ended third tubular section threadably coupled to an outer surface of said first tubular section and threadably coupled to an outer surface of said second tubular section, wherein rotation of said third tubular section in a first direction causes said first tubular section and said second tubular section to move axially towards one another, and wherein rotation of said third tubular section in a second direction opposing said first direction causes said first tubular section and said second tubular section to move axially away from one another.
