Abstract
Description
この構成では、ブロアが駆動している間、補助孔に対向するフィルムの領域が、第1通気孔からバルブ室への吐出風によって、補助孔側へ変形する。これにより、第1の板とフィルムの当該領域との隙間が大きくなる。すなわち、第2の板が補助孔を有さない場合と比べて、バルブの流路抵抗が小さくなり、気体の流量及び圧力が増大する。
以下、本発明の第1の実施形態に係る流体制御装置111について説明する。
次に、本発明の第2の実施形態に係る流体制御装置211について説明する。
次に、本発明の第3の実施形態に係る流体制御装置311について説明する。
次に、ブロア部13が駆動している間における、流体制御装置111の吐出性能と比較例の流体制御装置の吐出性能とを比較する。比較例の流体制御装置が流体制御装置111と相違する点は、天板21が補助孔49を有さない点である。その他の構成に関しては同じであるため、説明を省略する。
次に、ブロア部13が駆動している間における、流体制御装置211の吐出性能と補助孔を有さない比較例の流体制御装置の吐出性能とを比較する。
なお、前述の実施形態では、流体制御装置111、211、311は、ブロア部13を備えているが、これに限るものではない。実施の際、流体制御装置111、211、311は、異なるブロア部を備えていてもよい。
