Abstract
A spray arm for a dishwasher includes an outlet nozzle which is provided on a bottom side of the spray arm for emptying washing liquor from the spray arm. The outlet nozzle is selectively closed and opened by a valve which is movable from an open position into a closed position in response to a pressure of the washing liquor. The valve is pretensioned in a direction to seek the open position so that the valve automatically opens when the pressure of the washing liquor drops below a predetermined value.
