1. An apparatus for supplying a selected gaseous component, the apparatus comprising:

  • a separating means for separating the selected gaseous component from a gaseous mixture, the separating means providing the selected gaseous component at a relatively low separated gas pressure;

    a first one-way valve means for permitting the separated gaseous component to flow from the separating means to a first pressurizing means and for inhibiting the flow from the first pressurizing means to the separating means;

    the first pressurizing means cyclically receives the selected gaseous component at the relatively low separated gas pressure and increases the pressure of the received selected gaseous component with a first preselected pressure;

    a second one-way valve means for permitting the separated, pressurized gaseous component to flow from the first pressurizing means to a second pressurizing means and blocking the flow from the second pressurizing means to the first pressurizing means;

    the second pressurizing means (i) continuously pressurizes the received, selected gaseous component, (ii) to a preselected second pressure, which second preselected pressure is less than the first preselected pressure.
