ABSTRACT:
A device (1) for varying the valve timing in an internal combustion engine having a hydraulically displaceable annular piston (9) comprises a locking piston (15) arranged adjacent to a pressure chamber (14) which is situated in front of the annular piston (9) and to facilitate a displacement of the locking piston (15) in its uncoupling direction by hydraulic medium, a vent passage (27) leads out of a pressure chamber (26) situated axially behind the locking piston (15) for evacuating the air collected in this pressure chamber (26) into the open.
