Abstract (en)
[origin: WO2014016023A2] The invention relates to an electromagnetic positioning device having an armature unit (18) that can be actuated as a reaction to a current supply of a stationary coil unit (14) relative to a stationary core unit (10), which armature unit has permanent-magnetic means (28) and a tappet unit (31) that is led out of a magnetically flow-conducting housing (35), wherein on the shell side of a shaft section (20) of the armature unit (18) magnetically non-conducting socket means (32) are provided in such a way that in a state of the coil unit (14) in which no current is supplied a permanent-magnetic flow (40) of the permanent-magnet means (28) flows through the core unit (10) and the shaft section (20) for retaining the armature unit (18) on the core unit (10) and in a state of the coil unit (14) in which current is supplied the permanent-magnetic flow (40', 40") is displaced from the core unit (10) into a housing section (50, 52) of the housing and a permanent-magnetic flow circuit is closed via a section (54) of the tappet unit on the housing side.
