Abstract
Official abstract text for this publication.
A solenoid device includes at least one electromagnetic coil for generating a magnetic flux when energized, a fixed core constituting part of a magnetic circuit through which the magnetic flux passes, and plungers constituting the magnetic circuit together with the fixed core and configured to advance to and retract from the fixed core depending on whether the magnetic coil is energized or de-energized. The magnetic circuit is provided with a magnetic resistance part as a resistance for the magnetic flux. The plungers are configured to be attracted to the fixed core by energizing the electromagnetic coil.
First claim
Opening claim text (preview).
What is claimed is: 1. A solenoid device comprising: at least one electromagnetic coil for generating a magnetic flux when energized; a fixed core constituting part of a magnetic circuit through which the magnetic flux passes, the fixed core being comprised of a center core, two opposing cores, two top cores and two bottom cores; and plungers constituting the magnetic circuit together with the fixed core and configured to advance to and retract from the fixed core depending on whether the electromagnetic coil is energized or de-energized; the magnetic circuit being provided with a magnetic resistance part as a resistance for the magnetic flux, the magnetic resistance part is formed in each of the bottom cores of the fixed core; the plungers being configured to be attracted to the fixed core by energizing the electromagnetic coil. 2. The solenoid device according to claim 1 , wherein a multi-attracting state where the plungers are attracted to the fixed core is maintained while the electromagnetic coil is energized. 3. The solenoid device according to claim 1 , wherein the plungers are magnetically parallel-connected through the fixed core. 4. The solenoid device according to claim 1 , wherein the magnetic resistance part is formed by a gap dividing the fixed core in a direction of the magnetic circuit. 5. The solenoid device according to claim 4 , wherein a low magnetic permeability member whose magnetic permeability is lower than that of the fixed core is disposed in the gap. 6. The solenoid device according to claim 1 , wherein the electromagnetic coil is disposed at a plurality of locations.
