  • Reciprocating feed system for fluids
    Patent number: 6314978
    Abstract: To produce a high pressure stream of fluid, such as propellant, the fluid is transfered from a low pressure reservoir into a plurality of intermediate storage tanks, in which the fluid is pressurized. The fluid is drained from the storage tanks to an outlet in sequence. While one pressurized storage tank in a three pressurized tank system is being drained, the most recently drained one of the storage tanks is being vented, and still another of the storage tanks is being filled or replenished with fluid, as the case may be, from the low pressure reservior.
