Abstract

Es werden eine Hochdruckkraftstoffpumpe mit entlüftetem Membranspeicher (31) vorgeschlagen, bei welchem ein erster Teilraum (39) des Membranspeichers (31) mit einem Kraftstoffrücklauf über eine Drossel (49) in Verbindung steht. Dadurch ist es möglich, eine Membran (35) einzusetzen, die nicht diffusionsdicht gegenüber Kraftstoff ist, aber ansonsten bessere Eigenschaften als diffusionsdichte Membrane aufweist.
