    • A spring member extending from a first end to a second end about a longitudinal axis, the spring having an inherent bias to assume an extended position with a first end spaced from the second end along the axis, the spring assuming compressed positions when compressed by forces applied parallel to the axis, in the compressed positions the spring resiliently urges its first and second ends axially away from each other toward the extended position, the spring member having a wall in the shape of a solid of revolution rotated about the axis and defining a central cavity therein open at the first end of the spring and substantially closed at the second end of the spring, the wall when in the unbiased extended position having a greatest diameter at the first end and a least diameter at the second end, a plurality of openings through the wall, the openings disposed symmetrically both circumferentially and axially relative to each other.
    • 弹簧构件从第一端延伸到围绕纵向轴线的第二端,弹簧具有固有偏压以呈现延伸位置,其中第一端沿着轴线与第二端部间隔开,弹簧在被力压缩时被假定为压缩位置 平行于轴线施加,在压缩位置,弹簧弹性推动其第一和第二端部朝向延伸位置轴向地远离彼此,弹簧构件具有围绕轴线旋转的实心形状的壁,并且限定一个 其中的中心空腔在弹簧的第一端处开放,并且在弹簧的第二端处基本上封闭,当处于无偏位延伸位置时的壁在第一端具有最大直径且在第二端具有最小直径,多个 穿过壁的开口,开口相对于彼此沿周向和轴向对称设置。
