Abstract

1498724 Washing machines AWECO APPARATE-UND GERATEBAU GmbH & CO KG 3 April 1975 [11 April 1974] 13715/75 Heading D1A The nozzle 6 provided on a water using device is of such a size and shape that it lies within the area of the output 8 from the supply nozzle 2 so that it receives water from the supply while peeling off part of the flow therefrom and preventing nozzle 6 from drawing in air. Fresh water feed line 4 is connected through magnetic valves 5a, 5b to spray nozzles 2 mounted in the upper side of a housing 1 and accurately aligned with nozzles 6 in the lower side connected to lines 7a, 7b leading to a water softener.
