Abstract
The invention concerns a device for the angular adjustment of a camshaft relative to the crankshaft of an internal combustion engine, particularly a vane-type adjuster ( ) comprising a stator ( ) that is driven by the crankshaft preferably through a traction element and a drive pinion ( ), and a vane rotor ( ) that can be pressurized by pressure oil and is rotationally fixed to the camshaft while possessing a means, preferably an axially displaceable fixing pin ( ) for effecting a releasable, rotational fixing of the vane rotor. The drawback of oil leakage in common vane-type adjusters is avoided by the fact that all components of the vane-type adjuster ( ) that have contact with pressure oil are arranged in an oil-tight housing ( ).
