Claims (9)
- 複数のチャンバ(4)(5)のそれぞれの開口部(2)(3)を接続し、かつ、前記複数のチャンバ(4)(5)のそれぞれの前記開口部(2)(3)を閉塞するための閉塞要素(6)(7)を備え、前記閉塞要素(6)(7)が、バルブハウジングの内部空間により構成される中間チャンバ(8)における閉位置において前記開口部(2)(3)を閉塞するため、縦駆動機構(9)により前記開口部(2)(3)に対応するバルブシート(10)(11)に対して押し付けられるように構成されているバルブ(1)の運転方法であって、
一の開口部(2)(3)を開放するため、当該一の開口部に対応する一のチャンバ(4)(5)の圧力を前記中間チャンバ(8)の現在圧力よりも高圧に調節し、これにより前記一の開口部に対応する一の閉塞要素(6)(7)を前記一の開口部(2)(3)に対応する一のバルブシート(10)(11)から離間させ、前記一のチャンバ(4)(5)および前記中間チャンバ(8)の間の圧力調節を実行することを特徴とする方法。 - 請求項1記載の方法において、
前記高圧状態における圧力を、前記縦駆動機構(9)および前記中間チャンバ(8)から前記一の閉塞要素(6)(7)に対して閉方向に作用する圧力を高くすることにより前記一の閉塞要素(6)(7)を前記一のバルブシート(10)(11)から離間させることを特徴とする方法。 - 請求項1または2記載の方法において、
他のチャンバ(4)(5)の他の開口部(2)(3)を閉塞している他の閉塞要素(6)(7)を、前記一の開口部(2)(3)の開放中に、前記縦駆動機構(9)および前記中間チャンバ(8)のうち一方または両方から作用する圧力により前記他の開口部(2)(3)に対応する他のバルブシート(10)(11)に対して押し付けることを特徴とする方法。 - 請求項1〜3のうちいずれか1つに記載の方法において、
前記高圧状態の実現に先立ち、前記一のチャンバ(4)(5)および前記中間チャンバ(8)のそれぞれの圧力が大気圧を基準として低圧状態とされ、前記一のチャンバ(4)(5)における前記高圧状態の実現のために大気圧を導入することを特徴とする方法。 - 請求項1〜4のうちいずれか1つに記載の方法において、
前記縦駆動機構(9)が前記閉塞要素(6)(7)が相対的にかつ相互に離れて変位可能であることを特徴とする方法。 - 請求項1〜5のうちいずれか1つに記載の方法において、
前記閉塞要素(6)(7)が前記縦駆動機構(9)とは相互に独立して変位可能であることを特徴とする方法。 - 請求項1〜6のうちいずれか1つに記載の方法において、
それぞれの前記閉塞要素(6)(7)には前記バルブ(1)の縦駆動機構(9)が割り当てられまたは設けられ、前記縦駆動機構(9)が共通の支持要素(12)に取り付けられていることを特徴とする方法。 - 請求項1〜7のうちいずれか1つに記載の方法において、
前記閉塞要素(6)(7)が前記縦駆動機構(9)により閉位置および中間位置の間で変位可能であり、横駆動機構(13)により中間位置および最大の開位置の間で変位可能であり、これにより前記閉塞要素(6)(7)は閉塞位置において前記バルブシートから離間した状態で前記開口部(2)(3)の間に配置され、最大の開位置において前記開口部(2)(3)の間の指定領域(14)から外れてまたは完全に外れて配置されることを特徴とする方法。 - 請求項8記載の方法において、
前記一の閉塞要素(6)(7)が前記一のバルブシート(10)(11)から離間する際に閉位置から中間位置に駆動されることを特徴とする方法。
