    • PROBLEM TO BE SOLVED: To provide a configuration capable of responding to a request of increasing the number of windings of a coil 8 or reducing a dimension in a radial direction in a linear solenoid 1 for which it is necessary to provide a respiration path for moving a fluid between the inside and the outside of a yoke 13.SOLUTION: In a linear solenoid 1, such a communication hole 15 is provided. Namely, the communication hole 15 is provided in a side part 13c to communicate inner and outer circumferences of a yoke 13 and overlapped with a space 31b in an axial direction. Thus, even without securing an annular gap between an outer circumference of a coil 8 and the side part 13c, a second respiration path 34 is formed from the communication hole 15 and a fluid can be moved between the inside and the outside of the yoke 13. Therefore, it is not necessary to wind the coil 8 around the annular gap conventionally required as the second respiration path 34 or the gap per se can be eliminated, thereby responding to a request of increasing the number of windings of the coil 8 or reducing a dimension in a radial direction.
    • 要解决的问题:为了提供能够响应于增加线圈8的绕组数量或减小线性螺线管1的径向尺寸的要求的配置,为此需要提供用于移动的呼吸路径 在磁轭13的内部和外部之间的流体。解决方案:在线性螺线管1中,设置有这样的连通孔15。 即,连通孔15设置在侧部13c中,以使轭13的内周和外周连通,并沿轴向与空间31b重叠。 因此,即使在线圈8的外周和侧部13c之间没有固定环状间隙的情况下,也可以从连通孔15形成第二呼吸路径34,并且可以在轭13的内侧和外侧之间移动流体 因此,不需要将线圈8卷绕在作为第二呼吸路径34的通常所需的环形间隙上,或者可以消除间隙本身,从而响应于增加线圈8的绕组数量或减少 径向尺寸。
