Abstract

Hydraulische Einrichtung (102,104) zur stufenlos variablen Verstellung einer Nockenwelle einer Brennkraftmaschine mit einem von einer Kurbelwelle angetriebenen, topfförmigen Außenrotor (114,116) und einem der Nockenwelle zugeordneten, zu diesem zwischen zwei Drehendlagen relativ verdrehbaren Innenrotor (202) mit Rotorflügeln (204,206,208,210,212,214), wobei in wenigstens einer Drehendlage Innen- und Außenrotor (114,116) miteinander drehfest verbindbar sind, wobei eine in einem Rotorflügel (214) angeordnete, zwischen einer Verriegelungs- und einer Entriegelungsstellung schaltbare Verbindungseinrichtung (232) mit in Rotorachsrichtung gerichteter Stellrichtung vorgesehen ist.
