Description
発明の利点
これに対して、請求項1に記載した特徴を有する本発明の高圧ポンプは、ローラ及び/又は支持部の摩耗が減少され、ひいては高い摩耗が避けられる、という利点を有している。
図1乃至図6には、内燃機関の燃料噴射装置のための高圧ポンプが図示されている。高圧ポンプは、複数部分より成るポンプハウジング10を有しており、このポンプハウジング10内に、内燃機関によって回転駆動される駆動軸12が配置されている。駆動軸12は、例えば駆動軸12の回転軸線13の方向で互いに間隔を保って配置された2つの軸受箇所を介して回転可能に支承されている。これらの軸受箇所は、ポンプハウジング10の種々異なる部分内に配置されており、例えば第1の軸受箇所がポンプハウジング10のベース体14内に配置され、第2の軸受箇所が、ベース体14に接続されたフランジ部15内に配置される。
