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 bauraumsparenden Konstruktion vorgeschlagen, daß der Schwenkhebel in seinen von einem Nocken einer Nockenwelle und einer Rückstellfeder bewirkten Schwenkbewegungen mittels eines koaxial zur Drehachse einer eine Kurvenscheibe zur Hubverstellung tragenden Steuerwelle drehbeweglich gelagerten Anlenkhebels geführt ist.
