螺线管装置
摘要：
本发明公开了一种螺线管装置（1），包括：第一电磁线圈（2a）；第一和第二柱塞（3a，3b），可根据第一电磁线圈的通电而移动；第一和第二固定磁芯（5a，5b），分别面对第一和第二柱塞；以及磁轭（4）。当第一电磁线圈未通电时，第一和第二间隙（G1，G2）分别形成在第一与第二柱塞以及第一和第二固定磁芯之间。当第一电磁线圈通电时，磁通在第一磁回路（C1）和第二磁回路（C2）中流动，第一磁回路经由第一间隙由第一柱塞、第一固定磁芯和磁轭提供，第二磁回路经由第一和第二间隙由第一和第二柱塞、第一和第二固定磁芯和磁轭提供，使得第一和第二柱塞被朝向第一和第二固定磁芯吸引。
摘要（英）：

A solenoid device (1) includes: a first electromagnetic coil (2a); first and second plungers (3a, 3b) movable according to energization to the first electromagnetic coil; first and second fixed cores (5a, 5b) facing the first and second plungers, respectively; and a yoke (4). When the first electromagnetic coil is not energized, first and second gaps (G1, G2) are formed between the first and second plungers and the first and second fixed cores, respectively. When the first electromagnetic coil is energized, the magnetic flux flows in a first magnetic circuit (C1) provided by the first plunger, the first fixed core and the yoke via the first gap, and a second magnetic circuit (C2) provided by the first and second plungers, the first and second fixed cores and the yoke via the first and second gaps, so that the first and second plungers are attracted toward the first and second fixed cores.
