    • PROBLEM TO BE SOLVED: To easily assemble a vibration control spring suitable for the vibration isolation of a working part of an expansion valve while securing its function.SOLUTION: An expansion valve comprises a vibration control spring 50 which energizes a shaft 33, and imparts slide resistance. The vibration control spring 50 includes: a base part formed of an annular plate having a hole 52 which allows the insertion of the shaft 33 in a center region; a plurality of spring parts 56 which are erected on the base part 54, and abut on an external peripheral face of the shaft 33; and a plurality of support pieces 58 which extend outwardly from the base part 54, and formed so as to be lockable to a body. The support pieces 58 include low-rigidity parts 58a which are lower than the base part 54 in rigidity.
    • 要解决的问题:为了容易地组装适用于膨胀阀的工作部件的隔振的振动控制弹簧,同时确保其功能。解决方案:膨胀阀包括振动控制弹簧50,其对轴33通电,并使滑块 抵抗性。 振动控制弹簧50包括:由具有允许将轴33插入中心区域的孔52的环形板形成的基部; 多个弹簧部件56,其竖立在基部54上,并抵靠在轴33的外周面上; 以及从基部54向外延伸并形成为可锁定到主体的多个支撑件58。 支撑件58包括刚性低于基部54的低刚性部分58a。

    • PROBLEM TO BE SOLVED: To provide a spring which can set a height low, and thus can cope with a small part with a small installation space.SOLUTION: An abutting part of a first cylindrical part 11 can enhance rigidity of an end part on the first member 101 side in the first cylindrical part 11 due to having a reinforcing part 21 projecting inward in the radial direction of a hole part 10A. An abutting part of a second cylindrical part 12 can enhance rigidity of an end part on the second member 102 side in the second cylindrical part 12 due to having a reinforcing part 22 projecting outward in the radial direction of the hole part 10A. Thus, even when lowering a height of the cylindrical parts 11 and 12, when elastically deforming corner parts 13 and 14 in impressing a load, deformation of the end part on the mating member side 101 and 102 in the cylindrical parts 11 and 12 can be prevented.
    • 要解决的问题:提供一种可以将高度设置得较低的弹簧,从而能够以小的安装空间处理小部件。 解决方案:第一圆筒部11的抵接部可以提高第一圆筒部11的第一部件101侧的端部的刚性,这是由于具有沿孔部的径向向内突出的加强部21 10A。 第二圆筒部12的抵接部由于具有从孔部10A的径向外侧突出的加强部22,能够提高第二圆筒部12的第二部件102侧的端部的刚性。 因此,即使在降低圆筒部11,12的高度的情况下,当使角部13,14在施加载荷时弹性变形时,圆筒部11,12中的配合部件一侧101,102上的端部的变形也可以是 预防。 版权所有(C)2012,JPO&INPIT
