PURPOSE:To perform high-speed and stable line passage by arranging a seal device, which has a supply port, in the suction and introduction port which introduces the lead wire or the induction wire of a Coanda spiral flow unite communication device, and providing a feeder, which consists of a roller, in front of it. CONSTITUTION:Connection ports 8 are connected to the suction and introduction ports of a plurality of Coanda spiral flow units 3 (two in the figure), and high- pressure gas is jetted along an incline 9 from the Coanda slit 4 of the distribution chamber 10 of each unit 3 so as to generate a spiral flow. A seal device 11, where a supply port 12 is provided at the center, is attached to the suction and introduction port 6 of the unit 3 at the first stage. The seal device 11 is made by sandwitching elastic plate with metallic plates. High-pressure gas is fed from the high-pressure gas source outside the figure to each distribution chamber 10. A feeder consisting of a pair of rollers is arranged in front of the seal device 11, and a lead wire or an induction wire 7 is passed through the unit 3 to the pipe outside the figure. Hereby, the damage by vibration is prevented and the high-speed line passage can be performed. |
