Abstract (en)
[origin: US8203405B2] An electromagnetic actuating apparatus with an elongate actuating element (3), which forms an engagement region (11) at the end and is capable of moving owing to the force of a coil device provided in stationary fashion, and sections of the actuating element have permanent magnets (4), which are designed to interact with a stationary core region (7), wherein a stationary bearing element (8) acting as a yoke is provided axially opposite the core region (7) for the actuating element (3), at least sections of which are in the form of a piston, wherein the actuating element (3) has two sections (10, 20; 3a, 3b), wherein a first section (19, 3a), which is arranged in the region of the permanent magnets (4), is optimized in terms of the magnetic conductivity and a second section (20, 3b), which is arranged in the engagement region, is optimized in terms of wear.
