A rotor connected to a camshaft, is rotated relative to a stator. Several radially protruding blades are inserted into the blade grooves (14) formed in the rotor. A rounded transition region is arranged between the side faces (15,16) and bottom (17) of the groove. The transition region is formed as circular arc segments (18,19) and as undercut to the side faces of the groove. |
