Abstract

1380670 Dish washers G BAUKNECHT GmbH ELEKTROTECHNISCHE FABRIKEN 2 Aug 1973 [9 Aug 1972] 36798/73 Heading A4F In a dish washer, a lower spraying pressure in the circulating washing liquid is achieved by the introduction of air at the intake of a centrifugal pump. In order to avoid air spaces forming on the pressure side of the pump with consequent damage to seal 12 due to hot running of the pump, one or more passages 17 is/are provided in the hub of impeller 9. Thus on rotation of the impeller 9 by shaft 10 washing liquid is directed to spaces 15 even when air is introduced at the intake nozzle 3 of the pump 4. The air is introduced via a pipe 13 having a valve 14, the consequential lowering of pressure allowing more delicate washing to be effected. The cross-sectional area of each opening 17 is between 0.1 and 10%, preferably 1 % of the area of the impeller.
