Pressure stabilizing output air cylinder

The invention provides a pressure stabilizing output air cylinder used for a pneumatic acting device. The pressure stabilizing output air cylinder comprises an air storage cylinder, an isolation plate, an acting cylinder, a piston and a piston rod. A circular hole is formed in the isolation plate. The piston rod is a variable-section rod. The piston rod penetrates the isolation plate and the air storage cylinder, and air in the air storage cylinder enters the acting cylinder through a gap between the piston rod and the circular hole of the isolation plate to act on the outside. The pressure stabilizing output air cylinder has the beneficial effects that when the piston moves, the flow of the air entering the acting cylinder is adjusted through the change of the section area of the piston rod so that the pressure of the acting cylinder can be maintained unchangeable, and the pressure stabilizing output effect is achieved. 本发明提供种稳压输出气缸，用于气动做功装置。所述的稳压输出气缸，包括贮气缸、隔离板、做功缸、活塞、活塞杆，其中隔离板上设置有圆孔，活塞杆为变截面杆，活塞杆穿过隔离板和贮气缸，贮气
