Description
簡単に言えば、本発明は、圧縮部と膨張部とを有するスクリュー・ロータ・ポンプを備えた真空ポンプであって、圧縮部からの排出部が、少なくとも一つのイジェクターと、イジェクターを介して圧縮ガスを排出するように連通しており、膨張部が、スクリュー・ロータ・ポンプ及びイジェクターを同時に作動させるように第1の弁手段を介して駆動ガス源に接続可能である真空ポンプを予見している。
Claims (10)
- 圧縮部(8,111)と膨張部(7,110)とを有するスクリュー・ロータ・ポンプを備えた真空ポンプであって、前記圧縮部からの排出部(10,118)が、少なくとも一つのイジェクター(1,103)と、イジェクターを介して圧縮ガスを排出するように連通し、前記膨張部(7,110)が、前記スクリュー・ロータ・ポンプ及び前記イジェクターを同時に作動させるように第1の弁手段(5,114)を介して駆動ガス源(P)に接続可能である、ことを特徴とする真空ポンプ。
- 前記弁(5,114)は、前記スクリュー・ロータ・ポンプ(7,8,110,111)を、前記イジェクター(1,103)を作動させるのと同じ駆動ガス源に接続するように配置され、前記弁は、前記イジェクターによって生成されたサブプレッシャーに応じて前記スクリュー・ロータ・ポンプを駆動するように開かれる、ことを特徴とする請求項1に記載の真空ポンプ。
- 第2の弁手段が、前記第1の弁手段が前記スクリュー・ロータ・ポンプを駆動するために開いているときに前記イジェクターへの排気路(4,106)を閉じるように配置されている、ことを特徴とする請求項1又は2に記載の真空ポンプ。
- 前記スクリュー・ロータ・ポンプの膨張部(7,110)は、前記イジェクターからの排出ガスを前記スクリュー・ロータ・ポンプを通って膨張した駆動ガスと混合するように、前記イジェクターの排出部(102)と連通している、ことを特徴とする請求項1に記載の真空ポンプ。
- 前記イジェクターは多段イジェクターである、ことを特徴とする請求項1から4のいずれか1項に記載の真空ポンプ。
