As a result, the drive element 18 is rotatably fixed connected to the output element 19. By moving the Adjusting piston 25 can be the angular position of the output element 19 compared to the drive element 18 and thus the Angular position of the intake camshafts 15, 15 'opposite the exhaust camshaft 14 can be changed. The adjustment of the adjusting piston 25 takes place against the force of one Spring 28 by pressurizing the left face of the adjusting piston 27.
