    • PROBLEM TO BE SOLVED: To provide a relief valve which is slim in comparison with a conventional one.
      SOLUTION: In this relief valve 20, a cylindrical movable valve element 30 is fitted inside of a cylindrical outer stem 21, and a communication space 20R is formed in a state of being penetrated through the outer stem 21 and the inside of the movable valve element 30. Whereby the compressed fluid flowing into the communication space 20R from one end of the outer stem 21 can be supplied to a sealed space (for example, internal space of tire) connected with the other end of the outer stem 21. As the movable valve element 30 is linearly driven in the flowing direction of the compressed fluid, that is, along the axial direction of the outer stem 21, the projection of the movable valve element to a side part from the outer stem, which is found in the conventional relief valve, can be prevented, and a structure slim in comparison with the conventional one, can be achieved.

    • 要解决的问题:提供一种与常规安全阀相比是苗条的安全阀。 解决方案:在该安全阀20中,圆柱形可动阀元件30装配在圆柱形外杆21的内部,并且连通空间20R形成为穿过外杆21和内侧的状态 通过从外杆21的一端流入连通空间20R的压缩流体可以被供给到与外杆21的另一端连接的密封空间(例如,轮胎的内部空间)。 由于可动阀元件30沿着压缩流体的流动方向(即沿着外杆21的轴向)被直线驱动,所以可动阀元件从外杆向外侧突出 在传统的安全阀中可以防止,并且可以实现与传统安全阀相比较的结构。 版权所有(C)2005,JPO&NCIPI
