GENERATION DEVICE OF PULSATION FLUID OR INTERMITTENT FLUID
PROBLEM TO BE SOLVED: To provide a device capable of generating a pulsation flow and an intermittent flow from a continuous fluid by pressure of the continuous fluid, without using an electric operation part.SOLUTION: A generation device comprises an injection mechanism 110 for injecting fluid of liquid or gas, a space cavity 120 being a closed space and filling the inside with outside air, a lower fluid discharge part 150 and a conducting hole 141 leading to a ventiduct 140. The injection tip of the injection mechanism 110 is in the vicinity of the conducting hole 141, and a part of an injection fluid flows downward while covering a sidewall face surface of including the conducting hole 141, and the injection fluid is formed so as to limit an airflow quantity of outside air from the conducting hole 141, and a strong-weak rhythm of blowing-in of the outside air is generated by a repetitive variation of temporary pressure reduction in the space cavity 120 caused when the injection fluid flows downward and temporary pressure recovery by blowing-in of the outside air from the conducting hole 141, and a pulsation flow or an intermittent flow of the fluid is generated from the injection mechanism 110.SELECTED DRAWING: Figure 2
【課題】電気的な稼働部分を用いることなく、連続流体の圧力により連続流体から脈動流や断続流を生成することができる装置を提供する。【解決手段】液体または気体の流体を噴射する噴射機構１１０と、閉鎖空間であり内部が外気で満たされた空間キャビティ１２０、下方の流体排出部１５０、通気路１４０につながる導通孔１４１を備えている。噴射機構１１０の噴射先が導通孔１４１の近傍であり、噴射流体の一部が導通孔１４１を含む側壁面表面を覆いつつ下方に流れて導通孔１４１からの外気の通気量を制限するよう噴射流体を形成し、噴射流体が下方に流れることにより生じる空間キャビティ１２０内の一時的な圧力低下と、導通孔１４１からの外気の吹き込みによる一時的な圧力回復との繰り返しの変動によって、外気の吹き込みの強弱リズムを生じせしめ、噴射機構１１０から流体の脈動流または断続流を生成する。【選択図】図２
