An inlet construction is provided which is particularly useful in a spray arm for a dishwasher. The inlet is formed of a circular opening in a bottom wall of the spray arm and a flat plate positioned within the hollow arm, above the opening and generally perpendicular to the direction of the liquid jet directed at the underside of the arm. The plate is held in place by being pressed against a plurality of spacers formed on the bottom wall of the arm by resilient fingers positioned adjacent to each of the spacers. The liquid jet strikes the plate and the liquid is forced radially outwardly into the arms of the spray arm to be ejected from openings in the spray arm.
An inlet in a bottom surface of a hollow interior spray arm member for a dishwasher having a central hub area and a plurality of arms extending approximately radially therefrom, said arms having holes therein from which wash liquid, received from a source of pressurized liquid in the form of a free jet not enclosed in a conduit, but directed along a path at said arm member, is to be ejected, said bottom surface consisting solely of a relatively flat surface, at least one of said holes and said inlet, said inlet comprising:
