AUTOMATIC GAS DISTRIBUTING DEVICE CONTROLLED BY A DIRECT APPLICATION OF HIGH GAS PRESSURE OF A SOURCE FOR SUPPLYING A PIPE WITH GAS FROM AN ALTERNATIVE GAS SOURCE

摘要

The automatic gas distributing device delivers gas at a constant predetermined pressure from one of several high pressure vessels arranged in a ring connecting. The device has flow paths corresp. to the high pressure vessels, and is controlled by the direct application of pressures of the gas contained in the associated vessels to the relevant stop valves. The device automatically sets into operation a high pressure vessel having a lower gas pressure than other vessels. The device interrupts the high pressure vessel in operation when the gas pressure of the vessel is reduced below a control pressure, and actuates the succeeding vessel.
