Abstract: A hydraulic camshaft adjuster for changing the control times of gas exchange valves of an internal combustion engine, designed as a vane cell camshaft adjuster. A control device inserted in the vane selectively opens and interrupts a flow connection between the working chambers. A locking device prevents relative motion between the rotor and the stator in that the rotor is fastened to the stator at a vane position. A switching valve, which has three working ports, a P port and a T port, can be moved into different control positions by an adjusting element,—wherein in the control position, the P port communicates with the working chambers via the A port, the B port is blocked at the switching valve, and the T port communicates with the control device of the vanes via the C port.

A locking device for excluding a rotational movement between the rotor and the stator locks the rotor to the stator in a vane position in which the volume of the two chambers is approximately equal, and includes a pin, interlockable with a stator-fixed component, designed to control the inflow and/or outflow of hydraulic medium to/from a chamber.
