Abstract

Flügelzellen-Nockenwellenversteller mit einem Stator, einem mit einer Nockenwelle verbindbaren Rotor mit mehreren radial abstehenden Flügeln, die in Flügelnuten eingesetzt sind, wobei eine Flügelnut Nutseitenflächen, einen Nutgrund und die Nutseitenflächen hinterschneidende, abgerundete Übergangsbereiche zwischen den Nutseitenflächen und dem Nutgrund aufweist, dadurch gekennzeichnet, dass die abgerundeten Übergangsbereiche zumindest teilweise als den Nutgrund (17, 35) hinterschneidende Kreisbogenabschnitte (18, 19, 33, 34) ausgebildet sind.

Figure imgaf001
A vane cam phaser having a stator, a rotor connectable to a camshaft having a plurality of radially projecting vanes inserted in vane grooves, a vane groove having groove side surfaces, a groove bottom and the groove side surfaces undercut, rounded transition regions between the groove side surfaces and the groove bottom, characterized in that the rounded transition regions are at least partially formed as circular arc sections (18, 19, 33, 34) which undercut the groove base (17, 35).
