The coil,or helical,spring consists of a wire or rod wound into a helix and is primarily intended for axial direct compression or tension loads. 卷簧，或者說螺旋形彈簧包括一條盤成螺旋形的金屬絲盤條，它起初是用於軸向直接壓力和拉伸。
The helical spring can no longer be used. 盤簧不能再用了。
After removing the first check from the backflow valve body, place on a flat surface with the coil spring facing up. 從防迴流閥閥體上拆卸第一止回閥后，要使螺旋彈簧面朝上放在平面上。
The multilink coil spring suspension wasn't too stiff or too loose, which would make the driver feel uncomfortable. 在多重螺旋彈簧懸架不是太硬或太松，這將使司機感到不舒服。
