Abstract

Vorrichtung zur Betätigung der Ladungswechselventile in Hubkolbenmotoren, bestehend aus einem Gehäuse (G), einem in einem Drehgelenk (ng) in dem Gehäuse umlauffähig gelagerten Nocken (N), dessen Drehbewegung von einer Kurbelwelle abgeleitet ist, einem von diesem Nocken über ein erstes Kurvengelenk (zn) betätigten Zwischenglied (z)und einem Abtriebsglied (A), welches die Bewegung auf das Ventil (V) überträgt und mit dem Zwischenglied direkt oder über weitere Übertragungsglieder wirkverbunden ist und innerhalb der Wirkverbindung vom ersten Kurvengelenk zum Abtriebsglied mindestens ein weiteres Kurvengelenk (za) vorgesehen ist, das an einem der beiden das Kurvengelenk an sich bildenden Getriebeglieder durch eine Kurve gebildet ist, deren Form in dem Kontaktbereich, in welchem das Ventil einen Ventilhub aufweist, der grösser als Null ist, mindestens einen Wendepunkt (W) aufweist.
