20090002109 | POLE TUBE AND ACTUATION MAGNET HAVING SUCH A POLE TUBE - A pole tube including a non-magnetic spacer ring configured to join a pole piece along a control cone and also configured to join a tube piece along a back annular surface. The annular surface includes a first face section and a second face section. The first face section and the second face section are disposed at an angle with respect to each other. | 01-01-2009 |
20100219919 | ELECTROMAGNETIC ACTUATOR WITH VARIABLE RELUCTANCE - The invention relates to an electromagnetic actuator with variable reluctance comprising a fixed ferromagnetic armature ( | 09-02-2010 |
20110050376 | Laminate Stack Comprising Individual Soft Magnetic Sheets, Electromagnetic Actuator, Process for Their Manufacture and Use of a Soft Magnetic Laminate Stack - A laminate stack having individual soft magnetic sheets. The individual sheets are involutely curved in the laminate stack. Each individual sheet has a first long side, a second long side opposite the first long side, a first short side and a second short side opposite the first short side. The first long side has a recess, said recess being rectangular and equidistant from the first short side, the second short side and the second long side when the individual sheet is in its uncurved state. | 03-03-2011 |
20120038439 | Laminate Stack Comprising Individual Soft Magnetic Sheets, Electromagnetic Actuator, Process for Their Manufacture and Use of a Soft Magnetic Laminate Stack - A laminate stack having individual soft magnetic sheets. The individual sheets are involutely curved in the laminate stack. Each individual sheet has a first long side, a second long side opposite the first long side, a first short side and a second short side opposite the first short side. The first long side has a recess, said recess being rectangular and equidistant from the first short side, the second short side and the second long side when the individual sheet is in its uncurved state. | 02-16-2012 |
20130181795 | ELECTROMAGNETIC VALVE - An electromagnetic valve includes a coil that generates a magnetic force, a stator core arranged radially inward of the coil, an armature moved toward the stator core in an axial direction of the coil by the magnetic force, a yoke arranged on radially outward of the coil, a housing axially contacting the yoke and including a slide hole supporting the armature slidably, and a ring-shaped magnetic plate. The ring-shaped magnetic plate faces to the armature on a radially inner side of the magnetic plate, and faces to the yoke via a clearance on a radially outer side of the magnetic plate. The magnetic plate radially contacts the housing on the one side in the axial direction with reference to a position where the yoke contacts the housing, and on a radially outer side of an inner surface of the slide hole. | 07-18-2013 |
