Abstract (en)
A rotating spray arm (8) with main spray nozzles (10) and at least an auxiliary spray nozzle (12) is supplied by a circulation pump (13) through a sequence of alternating periods and pauses in which the pressure of the water supplying the rotating spray arm is at its highest and its lowest value, respectively. A hydraulically operated valve (21) shuts off the auxiliary nozzle (12) during said pauses only. <IMAGE>
