ABSTRACT:
A regulator for the control of high pressure gases comprises a first piston type regulator stage and a one piece resilient flow control washer which serves as a second regulating stage. The flow washer comprises a resilient element having an orifice therein through which the regulated gas passes. The washer is shaped and mounted so that gas pressure variations deform the washer and vary the size of the orifice to maintain a constant gas flow rate therethrough.
