Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electromagnetic solenoid comprising:
a stator including a stator core;
a coil configured to generate an electromagnetic attractive force by energizing the stator core;
a mover configured to be attracted toward the stator by the electromagnetic attractive force; and
a magnetic elastic admixture including a resin material with soft magnetism and elasticity,
wherein the mover is configured to reciprocate by being released by an elastic body that generates a biasing force in a direction opposite to a direction in which the electromagnetic attractive force acts,
a proximal end of the mover is located at a first proximal end position upon the mover being electromagnetically attracted toward the stator during energization of the coil, and is located at a second proximal end position upon the mover being electromagnetically released and moved to a side opposite to the stator during de-energization of the coil, and
the magnetic elastic admixture is configured to elastically deform between the mover and the stator and not to be separated from a contact surface with the mover and a contact surface with the stator.
