And likewise the deceleration can be controlled by slowing down the speed of spool movement back to the centre condition.
同样地，减加速度也能够被控制，使阀芯运动回中位的速度变慢。
The instantaneous opening of the vent valve in the opening process is large and the spool movement is affected by the stop device.
排油阀开启过程瞬时开度大且阀芯运动受限位装置影响。
By varying the current to either solenoid, the amount of spool movement can be varied and hence the amount of flow through the valve can be controlled.
通过改变两个之一电磁铁的电流，阀芯移动的位移能够被改变，因此控制了通过阀的流量。
