Abstract (en)

[origin: EP2273077A1] The device has a drive element driven by a crankshaft and rotatably supported opposite to a camshaft. A torsion spring is arranged between the camshaft and the drive element for retracting adjustable angular rotation between the camshaft and the drive element in an initial position. Ends of the torsion spring are arranged in recesses (5) of the camshaft, and a guide connecting rod is arranged at a ring or flange-shaped section (6) of the drive element at a distance to a rotational axis (D) of the camshaft, where one of the recesses is formed at an end of the connecting rod.
