  • the apparatus To operate the apparatus, the apparatus is first filled with water and as the water reaches the dotted line X-Z the tloat rises and closes the valve. Air is discharged through the relief valve 25 which is subsequently closed. The mixture of oil and water is then admitted, and the separator comes into action. The oil rises as described, and the water flows on and out of the rising pipe or water leg 4.
  • the oil outlet As the water discharge level is above the discharge level ot the oil outlet, there is always a working head or pressure at theoil outlet. As the oil collects inthe head or dome it gradually displaces the water, and eventually when suliicient oil has collected, the float is no longer supported on water, and falls, opening the valve. The oil is then forced out hen the oil accumulates down to the level Y-Y, or it air' accumulates, the float operates the oil outlet.
