    Abstract: A decelerating air circuit having an air cylinder is disclosed. The decelerating air circuit includes a driving solenoid valve having an advance mode and a withdrawal mode. A decelerating solenoid valve having a high speed mode and a low speed mode has an outlet port connected to the decelerating solenoid valve. A constant speed flow control valve is attached to a low speed port of the decelerating solenoid valve. Limit switches are located respectively at an advance end and a withdrawal end of a piston rod of the air cylinder. Decelerating sensors are located respectively between the limit switches. The piston rod advances past a point of a decelerating sensor, triggers the sensor, and causes the decelerating solenoid valve's operating mode to change from a high speed mode to a low speed mode. The change in mode is accomplished by outgoing air being introduced so that it passes through the flow control valve thereby reducing the speed of the piston rod.
