摘要： An electromagnetic valve device capable of reducing the number of assembled parts and manufacturing cost thereof includes a stable core arranged in a solenoid, a movable core slidable in the solenoid to form a magnetic gap with the stable core, a casing made of magnetic material and provided with a holder portion extending along the outer periphery of the solenoid and a yoke portion extending inside of the solenoid in sliding contact with the movable core, and a base made of synthetic resin unitedly molded with the casing and opposed to the movable core so as to form a valve member with the movable core. The yoke portion of the casing can sufficiently contact the movable core so as to allow the movable core to act as a valve with the base in association with a return spring for normally biasing the movable core toward the base. The casing and the base are unitedly molded to prevent positional deviations of the axial centers therebetween so that the base and the movable core can properly serve as a valve to open and close a fluid passage with less leakage therefrom.

摘要翻译： 能够减少组装部件数量和制造成本的电磁阀装置包括布置在螺线管中的稳定芯，可在螺线管中滑动以与稳定芯形成磁隙的可动芯，由磁性材料制成的壳体 具有沿着螺线管的外周延伸的保持部和与可动芯滑动接触的螺线管内部的轭部，以及与壳体一体成型并与可动铁芯相对的合成树脂制的基座， 形成具有可动芯的阀构件。 壳体的轭部可以充分地接触可动芯，以便允许可动芯作为与底座相配合的阀，与复位弹簧相配合，用于使可动芯向基座正常偏置。 壳体和基座被一体地模制以防止它们之间的轴向中心的位置偏离，使得基部和可动芯可以适当地用作阀，以便以较少的泄漏从而打开和关闭流体通道。
