Description
溝がガス出口への通路の流出口を少なくとも一部包囲し、吸込室から投げ出された潤滑剤をその溝の中に受け取り、これにより吸込室内への落下が阻止される前記溝は、発生する騒音の明らかな低減のために有効である。吸込室からガス出口内へ投げ出された潤滑剤は回転翼形油回転真空ポンプの運転圧力付近で著しく脱気されている。通路およびガス出口もまたほとんどガスを含んでいないので、潤滑剤は蒸発することなくガスによる減速なしにハウジング部分に当たる。吸込室内に落下する潤滑剤は特に大きな騒音を発生させる。本発明の装置により、潤滑剤が流出口を包囲する溝内に受け取られることによって、この落下が阻止される。
第1の変更態様は溝の製作に関するものである。このために、ガス出口を、第1の直径を有する円筒室として形成し、および通路を、第2の直径を有して円筒形に形成することが有利である。円筒形は中ぐりにより特に有利に且つ簡単に製作される。

Claims (5)
- ガス入口と、ガス出口(51)と、吸込室(11)と、およびポンプ段ハウジング(10)とを有するポンプ段(17)を備えた潤滑剤シール式回転翼形油回転真空ポンプにおいて、
吸込室(11)およびガス出口の間に配置されている、ガス出口への通路(50)の流出口の周りの少なくとも一部に溝(54)が配置され、この溝内に、吸込室から投げ出された潤滑剤が受け取られ、これにより吸込室内への落下が阻止されることを特徴とする潤滑剤シール式回転翼形油回転真空ポンプ。 - ガス出口が第1の直径を有する円筒室を含み、および通路(50)が第2の直径を有して円筒形に形成されていることを特徴とする請求項1の回転翼形油回転真空ポンプ。
- 通路の、ガス出口を向く端部にリング(52)が配置され、リングはガス出口内に突出し、これにより、リング(52)およびポンプ段ハウジング(10)の間のガス出口の範囲内に溝(54)が形成されていることを特徴とする請求項2の回転翼形油回転真空ポンプ。
- リング(52)が締付リングであることを特徴とする請求項3の回転翼形油回転真空ポンプ。
- ガス入口と流体結合を形成しているガス配管(4)のガス配管中心線(42)が、ポンプ段内に配置されている軸中心線(41)に対して少なくとも部分的に平行でもなく、軸中心線に平行な面内に少なくとも部分的に位置してもいないことを特徴とする請求項1ないし4のいずれかの回転翼形油回転真空ポンプ。
