Abstract: The invention relates to a pneumatic cartridge CA that is constituted by a cylinder CY provided with two endpieces and having at least one opening. The cartridge has at least one automatically-closing transfer device CH1, CH2, TR provided to disengage the opening completely. Furthermore, the automatically-closing transfer device is arranged at one of the ends of the cartridge.

Abstract: Since the same water-repellent process is provided on the nozzle forming part and the outer circumferential part of the nozzle formation member, same process as for the nozzle forming part is needed for the outer circumferential part which is not limited for its structural demand thereby the manufacturing process is complicated and needs high cost. The first water-repellent layer 41 due to the first water-repellent process is formed on the surface of the nozzle forming part 31 formed the nozzle 4 of the surface of the nozzle plate 2, and the second water-repellent layer 42 due to the second water-repellent process different from the first water-repellent process is formed on the surface of the outer circumferential part (outer portion of surface) of the nozzle plate 2. Materials and processes, in which the second water-repellent layer can be formed using simple manufacturing process, can be selected for the second water-repellent process.
