Claims (3)
- 高圧側から低圧側へ流通する空気量の変化に関係無く該両側間の差圧を一定に保持するための差圧保持ダンパであって、
前記高圧側に連通する下側開口から前記低圧側に連通する上側開口に向かって拡幅された筒状のテーパー管と、
該テーパー管内に設けられたガイド棒に沿って上下方向に浮遊可能な浮き子と、
を備え、該浮き子は、上下に分離可能な2個の浮き子を備え、上側の浮き子は下側の浮き子より重量が軽くなるように構成されており、該浮き子の上下方向の浮遊によって該浮き子と前記テーパー管の内面との隙間の面積が変化することにより前記下側開口から前記上側開口へ前記テーパー管内を流通する空気量の変化に関係無く差圧を一定に保持可能なように構成されていることを特徴とする差圧保持ダンパ。 - 前記上側の浮き子は前記ガイド棒に対して所定の滑り抵抗を有して設けられている請求項1に記載の差圧保持ダンパ。
- 前記浮き子が設定高さ以上に上方へ移動しようとすると該浮き子に接触して該浮き子の上方への移動を拘束する浮き子安定手段を備えている請求項1又は2に記載の差圧保持ダンパ。
