Abstract
Eine Kraftstoffpumpe (16) umfasst mindestens zwei zyklisch arbeitende Förderelemente (44a). Diese fördern.ein erstes Fluid jeweils auf die eine Seite eines ihnen zugeordneten beweglichen Wandabschnitts (64a, 64b, 64c). Dessen andere Seite ist mit einem Einlass (34) und einem Auslass (36) für ein zweites Fluid verbunden. Um die radialen Abmessungen der Kraftstoffpumpe (16) bei hoher Förderleistung klein halten zu können, wird vorgeschlagen, dass die beweglichen Wandabschnitte (64a, 64b, 64c) in zueinander versetzten Ebenen (VI, IX, XI) angeordnet sind. A fuel pump (16) comprises at least two cyclically operating conveying elements (44a). These convey a first fluid each on one side of a movable wall section (64a, 64b, 64c) assigned to it. Its other side is connected to an inlet (34) and an outlet (36) for a second fluid. In order to be able to keep the radial dimensions of the fuel pump (16) small at high delivery rates, it is proposed that the movable wall sections (64a, 64b, 64c) are arranged in staggered planes (VI, IX, XI).
