Abstract
An actuator for a hydraulic valve of a cam phaser, the actuator including a magnet housing receiving a magnetized metal sleeve and a coil that is radially enveloped by the magnetized metal sleeve generating a magnetic field, wherein the coil is fixated in a non-magnetizable coil carrier that is positioned in a cavity of the magnet housing, wherein the coil carrier at least partially envelops a pole core and a pole core yoke that is axially offset from the pole core, wherein the pole core and a pole core yoke are positioned so that they radially define a non-magnetic sleeve, wherein the non-magnetic sleeve forms a divider wall between the cavity of the magnet housing and an inner cavity of the non-magnetic sleeve.
