Patent ID: 7377244

Claim:
A camshaft adjuster including a gear mechanism ( 11 ), a drive element ( 12 ) connected to the gear mechanism ( 11 ) for driving a camshaft, an output element ( 13 ) connected to the gear mechanism ( 11 ) for driving a camshaft of an internal combustion engine, an adjustment input ( 15 ) connected to the gear mechanism for controlling the phase position of the output element ( 13 ) relative to the drive element ( 12 ), and a brake mechanism ( 20 ) for braking the adjustment input ( 15 ) of the gear mechanism ( 11 ) for the adjustment of a phase position of the output element ( 13 ) connected to the camshaft at least in a first direction, and a contactlessly operating electromagnetic coupling mechanism ( 30 ) disposed between the drive element ( 12 ) and the adjustment input ( 15 ) for locking the adjustment mechanism in a particular phase relationship.
