The utility model belongs to the technical field of hydraulic pressure, a sequence action pneumatic cylinder is provided, including the hydraulic cylinder body, piston rod, bottom end cover, center tube, valve, piston and spring etc, the hydraulic cylinder is equipped with into on personally experiencing sth. Part of the body, the oil -out, be equipped with control port on the bottom end cover, the lower extreme of piston rod is opened there is the blind hole, the center tube passes the blind hole and fixes on the bottom end cover through screw thread backstop, center tube inner chamber and control port intercommunication, the valve passes through spring coupling by door closure and connecting rod composition, the connecting rod lower extreme and the center tube of valve, and the door closure of valve compresses tightly together with the center tube terminal surface under the effect of spring, piston bottom trompil diameter is lighter than the door closure diameter of valve, guarantees that the piston bottom can contact with the valve flange. The utility model discloses can realize sequence action control reliably, accurately, can guarantee to input the hydraulic oil flow of the execute component of subordinate oil circuit again, guarantee piston rod normal output thrust.
