Abstract

Verdrängerpumpe mit verstellbarem Fördervolumen, um eine das Kraftfahrzeug antreibende Brennkraftmaschine mit Schmieröl zu versorgen,
die Verdrängerpumpe mit einem Verstellventil (20), das folgendes umfasst:
- ein Ventilgehäuse (21),
- einen in dem Ventilgehäuse (21) beweglich gelagerten Ventilkolben (22) mit einer Wirkfläche (23) für einen Ventilstelldruck (P20) eines Fluids,
- eine Ventilfeder (25), die einer von dem Ventilstelldruck (P20) auf den Ventilkolben (22) ausgeübten Kraft entgegen wirkt,
- eine Verstelleinrichtung (27, 28), mittels der der Ventilkolben (22) in Richtung der vom Ventilstelldruck (P20) ausgeübten Kraft oder gegen diese Kraft verstellbar ist,
wobei der Ventilkolben (22) eine weitere Wirkfläche (24) für den Ventilstellruck (P20) aufweist und die Wirkflächen (23, 24) einander entgegen wirkend angeordnet und der Größe nach unterschiedlich sind, um dem Größenunterschied der Wirkflächen (23, 24) entsprechend eine auf den Ventilkolben (22) der Ventilfeder (25) entgegen wirkende Differenzkraft zu erzeugen.
