ABSTRACT:
A centrifugal separator for fuel oil contaminated by water and sludge particles includes an inlet 41, nested separator plates 15, a clean oil outlet 1, a separated water outlet 2, and sludge outlets 48 controlled by a valve cylinder 50 closed by a water pressure chamber 32 and opened by a water pressure chamber 31. When the sludge layer 28 builds up and closes off the water discharge passage 27, the trapped water similarly builds up and overflows into chamber 33 to force piston 36 downwardly. This opens a valve 38, 39 to allow water from chamber 24 to enter chamber 31 and force the cylinder 50 downwardly to open the sludge outlets. The water in chambers 31 and 33 is slowly bled off through vent nozzles, whereby water in chamber 23 enters chamber 32 to raise the cylinder 50 and close the sludge outlets, and enters chamber 34 to raise the piston 36 and close the valve 38, 39.
