Description
本発明は、特に自動二輪車用の燃料ポンプおよび燃料タンクを備えた燃料ポンプアセンブリに関する。
これに対して、請求項1に記載の特徴を備える本発明に係る燃料ポンプアセンブリは、燃料ポンプにおけるフィルタの組付けもしくは取外しが大幅に簡略化される、という利点を有している。したがって、フィルタのクリーニングまたは交換が簡単にされる。これにより、それに関連するコストも大幅に低減する。このことは、本発明によれば、フィルタエレメントを、燃料ポンプに、または燃料タンクに配置された中間構造部分に、燃料タンクの外部で直接に接触させることにより達成される。この場合、本発明に係る燃料ポンプアセンブリは、燃料ポンプと、少なくとも部分的に燃料ポンプが内部に配置されている燃料タンクと、燃料タンクの外部に配置されかつ燃料タンクに燃料接続している中間構造部分と、フィルタ室内に配置されたフィルタとを有している。本発明によれば、フィルタは、中間構造部分または燃料ポンプの外部に配置されている。燃料流は、燃料タンクの内部から中間構造部分の第1の開口を通って外方にフィルタ室内へ、かつフィルタ室からフィルタおよび中間構造部分の第2の開口を通って燃料ポンプの入口に向かって流れる。特に有利には、燃料ポンプが完全に燃料タンク内に配置されている。この場合、フィルタは、中間構造部分に配置されている。中間構造部分の存在は、該中間構造部分を顧客に特化した要求に適合させることができ、この場合にフィルタおよび燃料ポンプは標準化して製造され得る、という利点を提供する。
以下に図1に関連して、本発明の有利な実施の形態による燃料ポンプアセンブリ1を詳しく説明する。
