Abstract
A need exists for a tank regulator that can reduce a pressure of more than about 4,300 psi to a much lower pressure. The present disclosure describes a piston regulator that allows for pressure to be reduced from an inlet pressure of about 5,000 psi or more to outlet pressure of about 2,000 psi or less. The regulator includes intermediate chambers to provide step-down pressures along the piston. The internal chambers enable to hold pressure differentials between the high-pressure inlet and the low-pressure outlet. The pressure in the intermediate chambers is maintained by a pressure-limiting valve to control the pressure differentials across piston seals. These seals allow the piston to actuate while maintaining a seal between the various pressure chambers.
