Abstract

Official abstract text for this publication.

The invention relates to an electromagnetic actuating device ( 1 ) for a camshaft adjustment device of an internal combustion engine of a motor vehicle, with an elongated actuating element ( 2 ) forming an engagement region on the end side and movable by the force of a coil device ( 29 ) provided in a stationary manner, which actuating element preferably has in parts a cylindrical covering contour and penetrates a cut-out ( 8 ) in permanent magnet means ( 6 ) arranged on the shell side, which are constructed for cooperating with a stationary core region ( 5 ) comprising a core body ( 15 ), and which actuating element lies in a switching position with a contact surface ( 11 ), on the end side on the actuating element side, against a contact surface ( 10 ) on the core region side. Provision is made that the contact surface ( 11 ) on the core region side is formed at least in part by a contact element ( 16 ) fixed in the core body ( 15 ), which contact element is constructed from a material which has a greater hardness than the material of the core body ( 15 ).
