Abstract

Es werden verschiedene Druckbegrenzungseinrichtungen (56) vorgeschlagen, welche die Integration eines Druckbegrenzungsventils in eine Kraftstoffpumpe (30) einer Kraftstoffeinspritzanlage ermöglichen. Dabei werden über eine Ausgleichskammer (82) kurzzeitige Druckspitzen, die sich bei jedem Förderhub der Kraftstoffpumpe (30) ergeben, abgebaut und somit ein unerwünschtes Öffnen der Druckbegrenzungseinrichtung (56) im Normalbetrieb der Kraftstoffeinspritzanlage verhindert.
