By this means a slight change in theboiler pressure is made to cause considerable changein the oil pressure, and as the quantity of oil sup-plied to the burners varies with the oil pressure, thefires in all boilers are increased or diminished grad-ually and simultaneously. This variable oil pressureis then made to act on the diaphragms of the othertwo regulators. In the atomizing steam regulator, there are twodiphragms, one acted on by the controlling oil pres-sure and the other connected to the atomizing steampressure near the burners. These diaphragms areconnected by levers which, acting through the watermotor and connecting rod, operate a chronometer. G. E. Witt ImprovedBurner Governor.
