PURPOSE:To obtain the large deflection angle width of stream with short overall length without greatly lowering the quantity of wind, by simply opening and closing control ports. CONSTITUTION:When both control ports 17, 18 are communicated with the atmosphere, stream passing through a nozzle 7 goes ahead because pressure difference, which forms deflection to stream flowing out from the nozzle 7, is not generated between control chambers 13, 14. When the area of an opening at the control port 18 side is partially limited by means of a closing plate that is responding opened and closed by factors, such as, temp, etc., pressure difference that creates right deflection to stream flowing out from the nozzle 7 is generated between the chambers 13, 14. Thus, stream from the nozzle 7 forms deflection from the upper current side, and advances in the arrow head E direction. When further limiting the opening of the control port 18, stream creates mutual interference between a guide wall 9 and the stream, and the direction of stream is further deflected at maximum. |
