A high pressure spray gun for airless atomization of spray material comprising a safety head mounted on the spray nozzle. The safety head is formed with two parallel protector studs comprising two opposed ridges located transversely to the spray direction and forming a transverse gap through which the spray material has to pass. The ridges are each defined by one flat forwardly inclined surface on each stud and by a common cylindrical surface which forms a transverse part-cylindrical chamber in the safety head. The ridges are formed with opposed edges and prevent spray material from setting on the projector studs. |
