    • PROBLEM TO BE SOLVED: To improve a normally closed solenoid valve device provided with a damper chamber for reducing the vibration of the mover to minimize the entry of air into the damper chamber to thereby stabilize the damping performance of the damper chamber.SOLUTION: A cylinder 9 which has one end open and has an inner diameter smaller than the outer diameter of a barrel section 6a of a mover and a piston 10 which is displaced relative to a cylinder 9 by the movement of the mover 6 are provided to the valve housing 2 and the mover 6 of a normally closed solenoid valve in such a manner that cylinder 9 and the piston 10 correspond to the valve housing 2 and the mover 6. This forms a damper chamber 11 between the cylinder 9 and the piston 10 inserted in the opening of the cylinder 9. A restriction flow path 12 for allowing a working liquid within a valve chamber 4 to enter and exit from the damper chamber 11 is provided between the damper chamber 11 and the valve chamber 4.
    • 要解决的问题:为了改进设有阻尼室的常闭电磁阀装置,用于减小动子的振动,以最小化进入阻尼室的空气,从而稳定阻尼室的阻尼性能。 解决方案:具有一端打开并且具有小于移动件的筒部6a的外径的内径的缸9和通过移动件6的运动相对于缸9移动的活塞10 被提供给阀壳体2和常闭电磁阀的动子6,使得气缸9和活塞10对应于阀壳体2和移动器6.这在气缸9和气缸9之间形成阻尼室11 活塞10插入到气缸9的开口中。用于允许阀室4内的工作液体进入和离开阻尼室11的限制流路12设置在阻尼室11和阀室4之间。 P>版权所有(C)2012,JPO&INPIT
