Abstract
Die Erfindung bezieht sich auf einen Klimakompressor für ein Kraftfahrzeug, dessen Druckkammer (18) mit einem hochdruckseitigen Port (26) und dessen Saugkammer (16) mit einem niederdruckseitigen Port (24) verbunden ist, wobei zwischen der Druckkammer (18) und dem hochdruckseitigen Port (26) ein Rückschlagventil (28) angeordnet ist, dessen Ventilkörper (32) entgegen der bestimmungsgemäßen Kältemittel-Stromrichtung und in Schließrichtung des Rückschlagventils (28) durch eine Vorspannkraft vorgespannt ist, die eine erste Feder-Vorspannkraftkomponente aufweist, welche durch eine am Ventilkörper (32) einerseits und an einem Federwiderlager andererseits abgestützte Feder (34) erzeugt ist. Die Erfindung zeichnet sich dadurch aus, dass das Rückschlagventil (28) mit einer Vorspannungserhöhungseinrichtung ausgestattet ist, die dem Ventilkörper (32) eine zusätzliche Vorspannkraftkomponente aufprägt, wenn ein am hochdruckseitigen Port (26) anstehender Druck kleiner ist als ein am niederdruckseitigen Port (24) anstehender Druck.
