Its working principle
With the help of motor, the shaft presses the plunger in the plunger socket through the thrust bearing slantwise arranged on itself in its rotational process. With the return spring effect, it makes the plunger stay close to the thrust bearing. The alternation of the shaft and the return spring make the plunger do reciprocating motions, then become vacuum oil-absorb below the plunger. Finally, it makes the nozzle get continuous and even pressure oil.
