Abstract:
An electromagnetic positioning device (1), having a stationary spool unit (9), having a moveably guided anchor (2), which forms a positioning section (14) and which can be axially displaced along a displacement axis (V) in response to supplying the spool unit (9) with current, as well as having a one-part cup-shaped yoke-core element (3), which receives the anchor (2) and which includes a core section (5) as well as a yoke section (6) and which has a yoke-core bottom (4) extending perpendicular to the displacement axis (V) and a yoke-core sheath extending perpendicular to the yoke-core bottom (4) along the displacement axis (V), a longitudinally cut transition area (8) reduced in thickness and arranged between the core section (5) and the yoke section (6) being realized in the yoke-core sheath. It is intended that a guide pin (17) for the anchor (2) is fixed, preferably pressed in, in a, preferably centric, guide pin recess (18) in the yoke-core bottom (4) and protrudes axially into a, preferably centric, guide opening (13) of the anchor (2) and can be displaced relative to the anchor (2) during its displacement movement.
