Abstract

A suction arrangement for emptying a tank which contains lavatory waste or the like comprises a tubular suction piece 33 which is introduced into the tank in order to empty it by suction. To generate a vacuum in the interior of the suction piece 33, suction machinery 4 and a suction duct 29 are provided, which connect the interior of the suction piece 33 to the suction machinery 4. The arrangement includes means for conducting rinsing liquid to the suction piece 33, which comprise a nozzle arrangement which is designed to conduct rinsing liquid to the outer surface of the suction piece 33 so that the rinsing liquid flows along a considerable length of the outer surface of the suction piece to its end so as to clean the outer surface before the suction piece 33 is removed from the tank. <IMAGE>
