Abstract
(EN)
A solenoid (100, 100a to 100h) is provided with: a coil (20) which generates magnetic force when energized; a columnar plunger (30) which slides in an axis direction (AD); a yoke (10, 10b, 10d) disposed along the axis direction; a bottom part (14) facing a base end surface (34) of the plunger; and a stator core (40, 40a, 40g). The stator core is provided with: a magnetic attraction core (50) for magnetically attracting the plunger; a sliding core (60, 60a) which has a cylindrical core part (61, 61a) arranged radially outside the plunger, and a magnetic flux transfer part (65, 65a) which is formed radially outward from an end part (62, 62a) of the core part and performs transfer of magnetic flux between the yoke and the plunger through the core part; and a magnetic flux passage suppression part (70, 70g, 70h) for suppressing passage of magnetic flux between the sliding core and the magnetic attraction core.

La présente invention concerne un solénoïde (100 ; 100a à 100h) comprenant : une bobine (20) qui génère une force magnétique lorsqu'elle est excitée ; un piston en colonne (30) qui coulisse dans une direction axiale (AD) ; une culasse (10, 10b, 10d) placée le long de la direction axiale ; une partie inférieure (14) faisant face à une surface d'extrémité de base (34) du piston ; et un noyau de stator (40, 40a, 40g). Le noyau de stator comprend : un noyau d'attraction magnétique (50) pour attirer magnétiquement le piston ; un noyau coulissant (60, 60a) qui a une partie centrale cylindrique (61, 61a) placée radialement à l'extérieur du piston, et une partie de transfert de flux magnétique (65, 65a) qui est formée radialement vers l'extérieur à partir d'une partie extrémité (62, 62a) de la partie noyau et effectue un transfert de flux magnétique entre la culasse et le piston à travers la partie noyau ; et une partie de suppression de passage de flux magnétique (70, 70g, 70h) pour supprimer le passage de flux magnétique entre le noyau coulissant et le noyau d'attraction magnétique.
