Abstract

Für einen variablen Ventiltrieb, insbesondere für Brennkraftmaschinen, bei dem ein Steuernocken (2) einer Nockenwelle (3) über eine zwischengeschaltete Rolle (4) auf einen schwenk- bzw. kippbeweglichen Ventilhebel (6) zur Betätigung eines Hubventiles (7) einwirkt, wird zur Erzielung einer stufenlosen Steuerzeit- und Hubverstellung des Hubventiles (7) vorgeschlagen, daß die Rolle (4) bei einem Minimalhub über einen verstellbar gesteuerten Verstellhebel (9) im äußeren Endbereich des Ventilhebels (6) positioniert quer zur Nockenerhebung des Steuernockens (2) schwenkbar geführt ist.
