Abstract
Description
従来技術からは、例えばガソリン直噴システムを備えた内燃機関で使用されるピストンポンプが公知である。この種のピストンポンプは、ポンプシリンダとポンプピストンとの間にギャップシールを有している。ポンプシリンダおよびポンプピストンは、典型的にはステンレス鋼から製造されている。そのようなギャップシールは、ポンプシリンダおよびポンプピストンの製造と取り付けの際に高い精度を必要とし、これによって、高いコストが発生する。常に存在するギャップは、例えば使用される材料の熱膨張係数に基づいてそのサイズを任意に低減することができず、特に回転数が低い場合には、準最適な供給レベルとなる。
本発明の課題は、回転数が低い場合でも十分な供給レベルを有し、サイズが小さく低コストで製造が可能なピストンポンプを提供することにある。
