throttle pilot valve

基本解释

Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed.
常開：儅線圈通電時，先導孔關閉，閥上腔由活塞節流孔增壓和複位彈簧的推力，電磁閥關閉。

When the coil power, the pilot valve by the spring return, pilot hole closed throttle valve chamber pressurized by the piston return spring and thrust, the electromagnetic valve is closed.
儅線圈斷電時，先導閥芯靠彈簧複位，先導孔關閉，閥腔由活塞節流孔增壓和複位彈簧的推力，電磁閥關閉。
