Abstract
A camshaft adjusting device, including a vane cell adjuster having a stator connectable to a crankshaft and a rotor, which is rotatably supported in the stator and connectable to a camshaft. Webs on the stator, divide an annular space between the stator and the rotor into pressure chambers, wherein the rotor has a rotor hub and vanes extending radially outward from the rotor hub, which vanes divide the pressure chambers into two groups of working chambers having a different acting direction, into each of which working chambers pressure medium flowing in or out in a pressure-medium circuit can be admitted, and a central locking device for locking the rotor in relation to the stator. The central locking device has two spring-loaded locking pins in an accommodating space, and lockable in a locking slot secured to the stator and lock in the locking slot when the rotor rotates from the direction of an 'early' or 'late' stop position into the locking position from different directions, wherein the locking pin forms a valve device together with the particular accommodating space, wherein the locking pin is a step pin.
