Abstract: The invention relates to an actuator, in particular for valves, relays or similar, which has an electromagnet (10) with a solenoid (11), a magnet armature (12) that can be displaced between two end positions and a magnet yoke (13), in addition to an actuating plunger (14) which is driven by the magnet armature (12). The aim of the invention is to create a bistable actuator with low power consumption and negligible heating of current-bearing components, in particular after extremely long switching periods in both switching positions during the power supply. To achieve this, the electromagnet (10) is configured in such a way that its magnet armature (12) has a stable central position, midway between the two end positions that form the two switching positions of the actuator, said central position being attained from the two end positions by a supply of current to the solenoid (11). In addition, the actuator is provided with a bistable, mechanical blocking element (15), which acts on the magnet armature (12) or the actuating plunger (14) and is effective in the end positions of the magnet armature (12).

Abstract: A bi-stable solenoid includes a housing, a wire coil arranged within the housing, a first pole piece, a second pole piece, an armature slidably arranged within the housing, and a permanent magnet arranged within the armature between a first armature portion and a second armature portion. The first armature portion and the second armature portion are fabricated from a magnetically permeable material. Selective energization of the wire coil generates a wire coil flux path and is configured to move the armature between the first stable position and the second stable position. The first stable position is established by magnetic flux of the permanent magnet shorting through the first pole piece, and the second stable position is established by the magnetic flux of the permanent magnet traversing the wire coil flux path.

Abstract: The present invention pertains to the field of magnetic systems and more precisely to structures and materials for the magnetic conductors used in electromagnets. This invention can be used mainly in closure devices for locking vehicle locks, safes or doors in order to prevent any unauthorised access. This invention essentially relates to an electromagnet that comprises a magnetic conductor in the shape of a cylinder, wherein said cylinder is provided with a bottom and a cover and contains a magnetisation cartridge as well as an anchor having a portion made of a hard magnetic material. The use of this electromagnet in closure devices such as button-type or blocking devices enables the latter to have a more compact structure, a higher secrecy as well as a higher protection reliability against unauthorised access. This is due to the higher retention force of the closure members constituting the electromagnet.

Abstract: An electromagnet (400) defines a gap between a first polepiece (410) in the shape of the butt end of an elongate cylinder and a second polepiece (420) in the shape of a thick annular ring. A permanent magnet (440) having its poles aligned along the axis of the cylinder moves bidirectionally in the gap in response to alternate polarity energization of the electromagnet (400), serving as a prime mover. When the electromagnet (400) is not energized then the magnetic flux of the permanent magnet shunts an adjacent polepiece (400 or 420, as in the case may be), holding the magnet in place. Upon energization of the electromagnet the relatively strong magnetic flux of the permanent magnet (440) is switched by a relatively weak electromagnetic flux to pass through the electromagnet (400), exerting an electromotive force on the permanent magnet (440) and causing it to move. Typically a one-half gram samarium cobalt permanent magnet moves 0.38 mm in response to a 0.015 ampere 1.5 v.d.c. 20 millisecond current pulse (4.5 x 10-4 joules) and holds at 40± 2g's. dislodging acceleration at each of two stable positions where no power is consumed.

Abstract: In at least some implementations, an armature for a solenoid valve includes a tubular main body and a head. The main body has an axis, a first end and a second end spaced axially from the first end. An outer surface of the main body is spaced radially from the axis and extends between the first end and the second end, and an inner surface is spaced radially inwardly from the outer surface and defines a cavity within the main body. The head is formed from a different material than the main body and carried by the main body, the head enclosing at least part of the cavity in the main body. The armature may be used in a solenoid valve and may be driven by an electromagnetic field generated by a coil of the solenoid.

Abstract: The tactile feedback actuator generally has a stopper, a damper, a hammer path between the stopper and the damper, a coil element fixedly mounted relative to the hammer path, and a magnetic hammer guidingly mounted for movement along the hammer path. The magnetic hammer has two opposite ends. Each end of the magnetic hammer has a corresponding permanent magnet. The two permanent magnets have opposing polarities. The magnetic hammer is electromagnetically engageable by a magnetic field emitted upon activation of the coil element so as to be longitudinally slid along the hammer path in any one of two opposite directions depending on a polarity of activation of the coil element. The stopper has a striking surface adapted for stopping the magnetic hammer, and the damper is adapted for decelerating the magnetic hammer as the magnetic hammer is longitudinally slid towards the damper.
