冲程

The principal of buffer is described as follows.At impulsing down,the piston moves down and vacates the annular space.The pressure in respiratory cavity decreases to a certain level and the traveling valve opens.At that time,the liquids enter into traveling valve and cavity and the plunger is impulsed upward to carry out the gentle transient at the sudden change.When the upward impulsing begins,the respiratory cavity is subjected to pressure and the traveling valve closes.During the gradual pressure rising,the liquids in respiratory cavity effuse from the upper ventage and the sudden change of force-summing direction of plunger is relieved relying on the resistance of ventage.

其原理大致是：下冲程时，活塞向下运动，让出环形空间的体积，呼吸腔内压力下降，下降到一定水平后，游动阀打开，此时，游动阀和小孔同时进液，使柱塞在从上死点处突然改变方向向上运动时得到缓冲，实现了柔和过渡；当上冲程开始时，呼吸腔受压，游动阀关闭，在压力逐渐上升的过程中，呼吸腔内的液体从上部的小孔流出，并依靠小孔的阻力使柱塞受力突然换向得到缓冲。
