Valve motion is analyzed with different refrigerants in the compressor. It is discovered that density of refrigerant have great influence on the movementofvalve.
对制冷压缩机的气阀采用不同工质时的运动规律进行了研究。

The movementofvalveof the oil well pump has not been researched perfectly in theory, and the mathematical models used to describing the movementof the oil pump valve are too simple.
目前抽油泵泵阀运动规律的理论研究还很不完善,所采用的数学模型也过于简单。

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.
