A spray arm assembly for a dishwashing machine includes at least one arm rotationally mounted about an axis, the arm including an internal cavity for receiving a pressurized service fluid and being provided with a plurality of spraying nozzles for spraying service fluid from said arm in the form of spray jets. The arm is shaped so that its opposite ends radially extend from the rotation axis in a manner diametrically opposite to each other about the rotation axis. The spraying nozzles are numbered, sized and positioned such that a total flow rate of service fluid delivered in use by the spraying nozzles at each concentric nozzle location circumference traced about the rotation axis of the arm during a complete rotation of the arm increases as a function of the radius of said nozzle location circumference.
