摘要： 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.

摘要： An electromagnetic valve device with an armature unit (10) which is designed for carrying out an opening or closing operation of a fluid channel and, as a reaction to stationary coil means (18, 20, 22), which at least partially surround the armature unit, being energized, is driveable so as to be movable along an axial direction (12) relative thereto, wherein the coil means have a coil former (20) which forms a winding section (20) for a winding (22) to be energized, and the coil former forms an axially extending inner casing which is designed for guiding the armature unit and in the lateral surface of which slot- or groove-like channels (54) permitting drainage of an armature movement space are formed, wherein the coil former provides a channel outlet (56) for the channels (54) lying axially opposite an inlet- or respectively outlet section (24) of the fluid channel and on the end face, with which channel outlet blocking and/or deflection means against infiltrating intrusive media are associated.

摘要： A camshaft adjustment device comprising an electromagnetic actuator (3) having an armature that can be adjusted axially along an adjustment axis (5) for actuating a hydraulic valve for camshaft adjustment, and fastening means for fastening the actuator (3) on an engine element (3), wherein the fastening means comprise spring means (12), which tension the actuator (3) against the engine element (2) in a securing position (13), wherein the fastening means have positive-fitting means (8) as an anti-twist device for preventing a twisting movement of the actuator (3) in an installation position (7) relatively to the engine element (2), which are constructed and arranged in such a manner that the actuator (3) can be moved to the engine element (2) by means of a pure translational installation movement and wherein the spring means (12) in the securing position (13) bar a de-installation path for a purely translational de-installation movement of the actuator (3) opposite to the installation movement in such a manner that the same cannot be de-installed oppositely to the purely translational installation direction.
