    • PURPOSE: To simplify and facilitate assembling of magnets for monitoring the changed-over conditions of the valve element of a solenoid valve and simply mounting magnetic sensors in properly waterproof and dustproof conditions for detecting the approach of the magnets. CONSTITUTION: The solenoid valve for changing the flowing direction of a pressure fluid by the drive with pilot fluid pressure comprises ring magnets 13A, 13B fitted to a small-diameter portion 11a formed at the end of the valve element 11 and fixed to the end of the valve element with the press-in engagement of caps 14A, 14B which form contact faces with the pistons 14A, 14B. A storage chamber 30 is formed close to the magnets at the outside of a valve hole 10a of a valve body 10 for storing the magnetic sensors 31A, 31B. A cover 35 is mounted on the storage chamber 30 and the cover is provided with a connector 37 for delivering current carrying wires to pilot valves 20A, 20B and signal lines from the magnetic sensors.
    • 目的:为了简化和便于组装磁铁,用于监测电磁阀的阀元件的转换条件,并且只需将磁性传感器安装在适当的防水和防尘条件下,以便检测磁铁的接近。 构成:用于通过先导流体压力驱动的用于改变压力流体的流动方向的电磁阀包括安装在形成在阀元件11的端部处并固定到阀体11的端部的小直径部分11a的环形磁体13A,13B 阀元件具有与活塞14A,14B形成接触面的盖子14A,14B的压入接合。 存储室30形成在磁体传感器31A,31B的阀体10的阀孔10a的外侧的磁铁附近。 盖35安装在存储室30上,并且盖设有用于将电流承载线传送到先导阀20A,20B和来自磁传感器的信号线的连接器37。
