20110133576 | ELECTROMAGNETIC ACTUATING APPARATUS - An electromagnetic actuating apparatus having an electromagnetic actuating unit which can be operated in order to exert an actuating force for an elongated plunger unit, wherein the actuating unit is provided in a housing along its actuating direction. The actuator unit forms an engagement surface which is planar in places and can be moved axially in the actuating direction, at an engagement end facing the plunger unit, an end surface of the plunger unit on the engagement side interacts detachably with the engagement surface, and the plunger unit is seated by magnetic attraction with its end surface on the engagement side on the engagement surface of the actuator unit, wherein the plunger unit is preferably designed to be soft-magnetic and furthermore preferably composed of soft iron, in the area of the end surface. | 06-09-2011 |
20110266475 | ELECTROMAGNETIC ACTUATOR - An electromagnetic positioning device has a long stretched out anchor plunger section as well as an anchor having an anchor body section axially continuing the latter, which in order to magnetically interact with a core unit and by energizing a stationary provided coil device is movably designed relative to the latter. The core unit is designed in such a way that it at least sectionally encompasses the anchor plunger section as well as the anchor body section with an expanded diameter relative to the anchor plunger section. The core unit is a multi-part design in the axial direction with a stationary core section, an axially movable core section and a variable core gap between the stationary and movable core section, and the movable core section and anchor are designed and joined together via a driver in such a way that, in response to energization, the movable core section moves, causing the core gap to close, and the driver drives the anchor in the axial direction. | 11-03-2011 |
