Abstract
(EN)
This solenoid (100, 100a, 100b) comprises: a coil (20) that generates magnetic force by being energized; a cylindrical sliding core (60) arranged on the inner peripheral surface of the coil; a columnar plunger (30) that is arranged on the inner peripheral surface of the sliding core and that slides along an axial direction (AD); a bottomed cylindrical yoke (10, 10a, 10b) having a tube part (12) and a bottom part (14); a magnetic attraction core (50) that is arranged facing a distal-end surface (32) of the plunger and that magnetically attracts the plunger; and a magnetic flux delivery member (80) that is arranged on the outer peripheral side of an end part (62) of the sliding core that faces the bottom part, the magnetic flux delivery member delivering magnetic flux between the sliding core and the yoke. In a state in which the plunger is closest to the magnetic attraction core, the position of the proximal-end surface of the plunger along the axial direction is the same as the position of the end part of the sliding core along the axial direction, or is closer to the bottom part along the axial direction than is the end part.

La présente invention concerne un solénoïde (100, 100a, 100b) comprenant : une bobine (20) qui génère une force magnétique en étant alimentée ; un noyau coulissant cylindrique (60) placé sur la surface périphérique interne de la bobine ; un piston en colonne (30) qui est placé sur la surface périphérique interne du noyau coulissant et qui coulisse le long d'une direction axiale (AD) ; une culasse cylindrique à fond (10, 10a, 10b) ayant une partie tube (12) et une partie inférieure (14) ; un noyau d'attraction magnétique (50) qui est placé en regard d'une surface d'extrémité distale (32) du piston et qui attire magnétiquement le piston ; et un élément de distribution de flux magnétique (80) qui est placé sur le côté périphérique externe d'une partie extrémité (62) du noyau coulissant qui fait face à la partie inférieure, l'élément de distribution de flux magnétique délivrant un flux magnétique entre le noyau coulissant et la culasse. Dans un état dans lequel le piston est le plus proche du noyau d'attraction magnétique, la position de la surface d'extrémité proximale du piston le long de la direction axiale est la même que la position de la partie extrémité du noyau coulissant le long de la direction axiale, ou est plus proche de la partie inférieure le long de la direction axiale que de la partie extrémité.
