Patent ID: 8783527

Claim:
A pressurized fluid system comprising: a storage tank including a cavity configured to store fluid under pressure; a first conduit in fluid communication with the storage tank cavity and configured to direct fluid within the cavity downstream toward a supply line, the first conduit including a first inlet disposed at a first vertical position within the cavity and a first regulator disposed downstream from the first inlet, the first regulator permitting fluid flowing from the cavity having a pressure value above a first threshold pressure value to flow downstream toward the supply line and preventing fluid having a value below the first threshold pressure value to flow downstream toward the supply line, wherein the first conduit directs the fluid stored within the cavity toward the supply line when an operational pressure value of the cavity falls within a first predetermined pressure range; a second conduit in fluid communication with the storage tank cavity and configured to direct fluid within the cavity downstream toward the supply line, the second conduit including a second inlet disposed at a second vertical position within the cavity that is below the first vertical position and a second regulator disposed downstream from the second inlet, the second regulator permitting fluid flowing from the cavity having a pressure value above a second threshold pressure value to flow downstream toward the supply line and preventing fluid having a pressure value below the second threshold pressure value to flow downstream toward the supply line, and wherein the second conduit directs the fluid stored within the cavity toward the supply line when the operational pressure value of the cavity falls within a second predetermined pressure range; and a third conduit in fluid communication with the storage tank cavity, wherein the third conduit directs the fluid stored within the cavity toward the supply line when the operational pressure value of the cavity falls within a third predetermined range, wherein the first predetermined pressure range is greater than each of the second predetermined pressure range and the third predetermined pressure range.
