A spray machine with a driven rotor unit that carries at its periphery a multitude of bushings that are open at both sides and are arranged with their axes pointing in a direction with at least one direction component parallel to an axis of the rotor. The spray machine includes a filling opening at a filling arrangement, a pressurized air inlet opening, an ejection opening located opposite to the pressurized air inlet opening considered in direction of the axes of the bushings, whereby all of the openings are so arranged that when the rotor unit rotates, the openings of the bushings pass over the openings. The spray machine also includes sealing plate arrangements characterized by the fact that surface pressure between the sealing plate arrangements and the rotor unit in an area comprising the filling opening is lower than surface pressure of the sealing plate arrangements to the rotor unit in an area containing the pressurized air inlet opening and the ejection opening.
