A dish washing machine comprises a circulating pump, a spray container with two crockery baskets, respective spray arms fed by the circulating pump and each rotatably arranged to spray the respective crockery basket and a switch-over device to alternately connect each of the spray arms to the circulating pump. The switch-over device comprises a housing (1), connected by an inlet feed stub (2) to the circulating pump and by two outlet stubs (3,4) to the spray arms. A rotatable or pivotable distributor blade (6) is so journalled in the housing that the water current from the feed stub (2) is directed to either one of the outlet stubs or partial currents are directed to both outlet stubs during a steady transition from the closing of the one to the opening of the other throughflow path. <IMAGE> |
