Abstract (en)
[origin: JP2018069238A] PROBLEM TO BE SOLVED: To provide a new pneumatic sprayer assembly for a coating product which can supply a coating product under low pressure to a spraying area.SOLUTION: A pneumatic sprayer assembly for a coating product comprises: a pneumatic sprayer (8); and a supply line (14) for supply to the pneumatic sprayer from the source of a pressurized coating product. The supply line is connected to the source by its upstream end. The pneumatic sprayer comprises: a sprayer body (82); and a control valve for controlling the flow of the coating product toward a spraying area (Z8) for the product. The control valve comprises a needle (96) for selectively closing an outlet (982) of an inner volume (V82) of the sprayer body. The sprayer assembly defines a flow path (C) for the coating product, from the upstream end of the supply line (14) to an outlet hole (982) of the inner volume (V82). A restrictor (120) for restricting the flow of the coating product is mounted on the flow path to create a pressure loss upstream from the outlet hole (982).SELECTED DRAWING: Figure 6
