Abstract

1,257,101. Dishwashing machines. SIEMENS A.G. March 26, 1969 [March 26, 1968], No. 15926/69. Heading A4F. [Also in Division F1] A pumping arrangement for a dishwashing machine comprises a centrifugal pump 9 and a self-priming axial-flow pump 10 (see Division F1). Rotation of the shaft 8 in one direction causes the centrifugal pump to run in its forward direction and circulate water within the dishwashing machine, and causes the axial-flow pump to run in reverse to return leakage received through a rubber seal 12, back to a common collecting chamber of the machine via the pump inlet 10a. Rotation of the shaft 8 in the opposite direction causes the axialflow pump to run in its forward direction and discharge the water from the machine, and causes the centrifugal pump to run in reverse and return leakage received through the seal 12, back to the common collecting chamber via the pump inlet 9a.
