Abstract

A camshaft adjuster for motor vehicles has a stator and a rotor rotatable relative thereto between which pressure chambers are provided. Pressure medium is supplied in a controlled way via a valve to the pressure chambers in order to rotate the rotor relative to the stator. Mounting of the valve in the internal combustion engine of the motor vehicle is often difficult when mounting conditions are tight, sometimes even impossible. In order for the camshaft adjuster to be usable even in tight spatial conditions, the valve is arranged on the side facing away from the camshaft connection. The valve can therefore be arranged stationarily axially outside of the engine of the motor vehicle. The camshaft adjuster requires thus only little mounting space.
