Abstract

Für einen Ventiltrieb zur Steuerung des Gaswechsels in Verbrennungskraftmaschinen mit einer das Ventil (20) stets in seiner geforderten Stellung haltenden Ventilfeder, die zwischen dem Ventilfederteller und einem in Richtung der Ventilachse verstellbaren Ventilfederlager eingespannt ist, soll die Einstellung einer definierten Federvorspannung für jedes einzelne Ventil ausführbar sein. Hierfür ist vorgesehen, das verstellbare Ventilfederlager aus zwei ineinanderfassenden und gegensinnig verdrehbaren Stellringen zu bilden, von welchen der innere Stellring (102) eine Fläche zur Auflage der Ventilfeder aufweist und durch das Verdrehen gegen den äußeren Stellring (103) in Richtung der Ventilachse bewegbar ist. Die Stellringe weisen dabei Elemente zur Verhinderung einer Rückdrehung auf.
