Farther, the possibility of practical use is analyzed. According to the work characteristics of secondary refueling station`s compressor, the motion rule of the valve in high pressure stage is simulated by use of mathematical model. At the same time, the bounce velocity between valve plate and valve seat, the bounce velocity between valve plate and lift restrictor, the bounce between valve plate and spring are studied at different suction pressure. Based on these studies, it shows that the work characteristic of compressor valve will keep well under the change of suction pressure when the choice of valve parameter is reasonable, and advises that increasing the rigidity coefficient or decreasing lift properly will probably eliminate the delay-close phenomenon of the exhaust valve.
