摘要： A camshaft adjustment device which has a pinion and a drive part that is disposed in a pivoting manner relative thereto. The pinion and the drive part are operatively connected to each other via a pressure chamber that can be pressurized using pressure means. At least one locking device can mechanically couple the pinion and the drive part. The locking device is actuated by a pressure medium. The pressure chamber and the locking device are in a pressure medium connection to one another for regulating the pressure medium supply to the locking device and the pressure medium discharge therefrom by at least one regulating unit. The passage of the pressure medium can be blocked in a pressure-tight manner in the direction of the pressure chamber by at least one locking device disposed in the pressure medium connection.
