Description
大形の物体を洗浄する場合、噴流の噴出範囲(広がり範囲)が広ければ、少数の流体噴出装置の出口の近くで洗浄を行うことができるので、噴流の消費量が節減され、エネルギーの節約になる。小形の物体又は大形の物体の一部分を洗浄する場合には、噴流の噴出範囲を狭くして、洗浄に利用されない噴流を少なくすれば、エネルギーの節約になる。また、洗浄を行う場合、物体の表面の状態や除去すべき物体の種類によって、最も洗浄効率の高い噴流の発振周波数が異なると考えられる。

Claims (2)
- 下壁とカバーとの間に、入口ポートから供給された圧縮空気を噴射するノズル及び該ノズルから噴射される噴流を自己発振させるキャビティが形成されたキャビティ本体と、上記キャビティ本体に連結されて上記自己発振した噴流を大気に噴出する出口部を備えた出口部本体とを、分離可能に形成した流体噴出装置において、
上記キャビティを上記キャビティ本体の上面視において楕円形に形成し、上記ノズルを楕円形のキャビティの横幅の中心に開口させたものとし、
縦幅と横幅の比率の相違により噴流の発振周波数を異ならしめた複数のキャビティ本体を備え、
上記出口部本体と、上記複数のキャビティ本体のうちで用途に適した発振周波数を有するキャビティ本体とを組み合わせて接続可能にした、
ことを特徴とする流体噴出装置。 - キャビティの横幅の中心と出口部の横幅の中心とを合致させる位置決め手段を備え、キャビティ本体のキャビティ下流側端面と出口部本体の上流側端面とを該位置決め手段により位置決めして接続した、
ことを特徴とする請求項1に記載の流体噴出装置。
