Description
本発明は請求項1の上位概念に記載の、1シリンダ軸線に沿って相前後して配置された少なくとも2つの作業シリンダを備えた復動ピストン圧縮機であって、前記作業シリンダ内で各1つのピストンが軸方向で可動にガイドされており、これらのピストンが、軸方向で作動する共通のピストンロッドを有しており、該ピストンロッドが、前記作業シリンダ間の隔壁に設けられた貫通開口を通って延びている形式のものから出発する。
本発明は、作業シリンダのピストンロッドの領域を、専らピストンロッドの半径方向外側の周面と貫通孔の半径方向内側の周面との間に形成された軸方向のギャップシールの形の無接触式のシールによって相互にシールするという思想に基づいている。換言すると、ピストンロッドは別個の接触シールの介在無しで、貫通開口を通って延びていることが望ましい。この場合、作業シリンダ間にはある程度の漏れが発生するが、この漏れは相前後して配置された少なくとも2つの作業シリンダを備えた本発明による復動ピストン圧縮機の構成形式では妨げとはならない。それというのも、各作業シリンダはいずれにしろ圧縮空気で負荷されているからである。この場合、作業シリンダ間の隔壁に設けられる、冒頭で述べた欠点を伴う従来慣例の接触シールは省くことができる。
以下に、本発明の実施例を図面につき詳しく説明する。
Claims (4)
- 1シリンダ軸線に沿って相前後して配置された少なくとも2つの作業シリンダ(2,4;2′,4′)を備えた反転式の復動ピストン圧縮機(1;1′)であって、前記作業シリンダ内で各1つのピストン(6,8;6′,8′)が軸方向で可動にガイドされており、これらのピストン(6,8;6′,8′)が、軸方向で作動する共通のピストンロッド(10;10′)を有しており、該ピストンロッドが、前記作業シリンダ(2,4;2′,4′)間の隔壁(26,26′)に設けられた貫通開口(32;32′)を通って延びている形式のものにおいて、
前記作業シリンダ(2,4;2′,4′)がピストンロッド(10;10′)の領域において、専らピストンロッド(10;10′)の半径方向外側の周面と前記貫通開口(32;32′)の半径方向内側の周面との間に形成された軸方向のギャップシール(66;66′)の形の無接触式のシールによって相互にシールされており、
該無接触式のシールは、一方の作業シリンダ(2,4;2′,4′)から他方の作業シリンダ(2,4;2′,4′)へギャップシール(66;66′)を通って流入する漏れ流(76;76′)が、引き続くピストンロッド(10;10′)の反転運動に際して圧縮されるべき空気体積を拡大するよう形成されている、ことを特徴とする、無接触式のギャップシールを備えた復動ピストン圧縮機。 - ラビリンスギャップシールを形成するために、少なくとも前記貫通開口(32;32′)の半径方向内側の周面に、軸方向で互いに間隔をおいて配置された複数の半径方向溝(68;68′)が設けられている、請求項1記載の復動ピストン圧縮機。
- 各作業シリンダ(2′,4′)がそれぞれ1つの圧縮段に対応する、多段圧縮用の多段式の復動ピストン圧縮機(1′)として構成されている、請求項1または2記載の復動ピストン圧縮機。
- 請求項1から3までのいずれか1項記載の復動ピストン圧縮機(1;1′)を有する、圧縮空気作動式の車両用ブレーキ装置。
