Each coil is wound on the form, then the nut is removed... so that the end of the spool comes off and the coil can be removed.

每个线圈的形式伤口，然后螺母被删除…这样的结束阀芯脱落后的线圈可以被删除。

I used a long bolt as a shaft, and the end of the spool is held on with a nut.

我用很长的螺栓作为骨干，并在年底举行的阀芯是一个螺母。

While the linear motion is actuated by pressure difference of two end spool chamber.

阀芯的轴向运动则由两端阀腔的静压力推动。
