Because the hydraulic pressure from the uper tubing, both up and traveling valves will close, When the plunger go up, the stationary valve open and oil will go through the pump, since the bottom pressure is higher than the uper pressure, then the fluid will be forced to go through the stationary valve and flow into the tubing.
In the down stroke,the traveling valve open and the presure drive the oil go into the plunger from the side holeof the extractor, then go into the tubing.
