BFN 6731 SELF-SEALING VALVE ASSEMBLY TO FACILITATE UNPLUGGING OF A CENTRIFUGAL CLEANER ABSTRACT OF THE DISCLOSURE A self-sealing element is provided in the outer wall of the discharge chamber of a centrifugal cleaning apparatus opposite the rejects dis- charge outlet. When a blockage occurs at the discharge outlet, a long needle-like nozzle is inserted through the sealing element to the blockage. Water or air under pressure is expelled from orifices in the nozzle and breaks up the blockage. After the nozzle is withdrawn, the sealing element, which may be formed of a silicone rubber, reseals itself.
