  • Publication number: 20150238911
    Abstract: A method of mixing two fluids uses three open-ended tubular sections assembled to define a mixing valve. An axial relationship between two of the tubular sections is defined by the third tubular section. A first fluid is introduced into an annular channel defined by the tubular sections. A flow of a second fluid is introduced along a flow path through the tubular sections. The first fluid is drawn into the flow of the second fluid via holes linking the annular channel to the flow path.

  • Publication number: 20130098490
    Abstract: A gas manifold system includes a plenum that receives a gas at a positive pressure and a manifold having at least one exit port. One or more valves are disposed between the plenum and the manifold. When opened, the valve(s) permit a stream of the gas at positive pressure to flow from the plenum into the manifold. A baffle is disposed in the manifold between the valve(s) and the exit port(s). The baffle obstructs each stream of gas entering the manifold such that the gas is reduced to substantially zero pressure in the manifold at the exit port(s).
