Abstract

Für eine Vorrichtung zur Hubverstellung eines Gaswechselventils im Zylinderkopf einer Brennkraftmaschine, bei der ein gesteuert verstellbarer Schwenkhebel über eine eine Leerhubkurve und eine Hubkurve umfassenden Steuerbahn mittels eines Übertragungselementes auf ein Gaswechselventil einwirkt, wird zur Erzielung einer Bauraum sparenden Konstruktion unter Vermeidung eines reibungsbehafteten Verkantens vorgeschlagen, dass der Schwenkhebel einerseits während einer nockengesteuerten und gegen eine Rückstellfeder bewirkten Schwenkbewegung über eine hebelendseitige Linienberührung mit einer Kurvenscheibe und ferner über mit Stützflächen an Wellenabschnitten der Steuerwelle beiderseits der Kurvenscheibe andererseits gleitbeweglich zusammenwirkenden Schwenkhebel-Kulissen geführt ist, wobei die mit den Schwenkhebel-Kulissen zusammenwirkenden Stützflächen der Wellenabschnitte der Steuerwelle ballig ausgebildet sind.
