ABSTRACT:
A high pressure fluid source is connected to a primary orifice and a valved orifice of a binarily activated pressure regulator. The primary orifice alone supplies the fluid at a pressure below the minimum desired, and both orifices together supply the fluid at a pressure greater than the maximum desired. A sensor at the output is adjusted to open the binary valve when the minimum pressure is reached, and close the valve when the maximum pressure is reached, thus cycling between the two conditions.
