Times the force of the cylinder and multi-stage telescopic cylinder stretched out, the reduction, the different diameter of the plunger movement in what order? Why? Answer: The order of the piston the piston out of the first out, the small piston out. Because the pressure changes from low to high pressure first reached a large piston area multiplied by the load exercise can promote the lower pressure, stretched out over a large piston, the pressure continues to rise in order to achieve multiplied by the small piston area can promote the higher pressure load exercise. The order of the reduction is small when the first piston retracts, large piston retracts. Because the first load of the piston rod in a small role, the former level is a small piston cylinder piston, the small piston retracts, the promotion of the cylinder (large a piston) retracts.
