    摘要： An apparatus for adjusting the partial pressure of gaseous mixtures comprises a housing and piston. The housing defines a chamber coupled to an oxygen metering orifice, diluent metering orifice, vent port and gas outlet. The oxygen metering orifice provides oxygen to the chamber and the diluent metering orifice provides diluent gas to the chamber. The piston is movably positioned in the chamber and includes first and second sealing devices. The chamber is sectioned into a mixing chamber, a diluent chamber and a reference chamber located between the mixing chamber and diluent chamber. The diluent chamber receives a diluent gas referenced at ambient pressure and the reference chamber is charged with a gas having a reference pressure. The piston changes positions within the chamber depending on a force balance created by a pressure differential between the reference pressure and ambient pressure.

    摘要： A reduced pressure shut off assembly for an eductor mixing system wherein a vacuum shut off valve is activated by reduced pressure in a reduced pressure line connected to a container for a concentrate. In a preferred embodiment, an eductor and the vacuum shut off valve are positioned on top a vessel for storing a solution of the concentrate. The mixing system with the vacuum shut off valve is especially adapted to being used for mixing a chemical concentrate cleaning composition with water.
