Abstract
This gas pressure control system is intended primarily for testing gauges by providing an accurate static gas pressure over a wide range, preferably from zero to 10,000 pounds per square inch. The system is equipped with a pressure intensifier that operates automatically to raise the delivery pressure above the supply pressure when necessary. The supply may be a bottle of nitrogen under pressure of two thousand two hundred pounds per square inch, and the pressure intensifier is preferably a cylinder-and-piston motor-pump combination with a displacement ratio such as 70 to 1.
