Abstract

Verdrängerpumpe mit verstellbarem spezifischen Fördervolumen, umfassend:
  • a) ein Gehäuse (3), das eine Förderkammer (4) enthält, in die an einer Niederdruckseite der Pumpe wenigstens ein Einlass (5) für Fluid und an einer Hochdruckseite der Pumpe wenigstens ein Auslass (6) für Fluid münden,
  • b) wenigstens zwei in der Förderkammer (4) aufgenommene, drehantreibbare Förderräder (1, 2), die miteinander in einem Fördereingriff sind, um das Fluid von dem Einlass (5) zu dem Auslass (6) zu fördern, wobei die Förderräder (1, 2) so verstellbar sind, dass durch eine Verstellung der Förderräder (1, 2) relativ zueinander oder relativ zu dem Einlass (5) und/oder dem Auslass (6) das spezifische Fördervolumen der Pumpe verstellt wird,
  • c) einen Kolben (7/8; 25), der für die Verstellung der Förderräder (1, 2) mit wenigstens einem der Förderräder (1, 2) gekoppelt ist,
  • d) einen ersten Druckraum (9) und einen zweiten Druckraum (10) für eine Beaufschlagung des Kolbens (7/8; 25) je mit Fluid der Hochdruckseite, wobei ein auf den Kolben (7/8; 25) wirkender Fluiddruck (P9) des ersten Druckraums (9) einem auf den Kolben (7/8; 25) wirkenden Fluiddruck (P10) des zweiten Druckraums (10) entgegenwirkt,
  • e) eine erste Fluidverbindung (11), die den ersten Druckraum (9) mit der Hochdruckseite verbindet, und eine zweite Fluidverbindung (12), die den zweiten Druckraum (10) mit der Hochdruckseite verbindet,
  • f) ein Federelement (13), das dem in dem ersten Druckraum (9) auf den Kolben (7/8; 25) wirkenden Fluiddruck (P9) entgegenwirkt,
  • g) und einen Regler (15), der den Fluiddruck (P10) des zweiten Druckraums (10) in Abhängigkeit von einer für die Fluidförderung der Pumpe maßgeblichen Regelgröße (PR) der Hochdruckseite regelt.
