Abstract
The invention is about an improved structure for gas flow control valve. One end of the valve is arranged with the primary and secondary spaces. A gas inlet arranged on the side of the valve is connected to the gas tank. A control element slides between the first and second locations. A convex ridge is formed between two ends of the control element. A hole is placed near one opening of the control element. A convex portion is formed on the rim inside of the hole and a concave portion is formed on the inner rim of the convex ridge. A spring is inserted between the convex and concave portions. The closed end of the spring takes the shape of a line; the other end of it is attached to a ball. A stopper at the closed end of the spring is placed in the concave area of the control element so that the spring can be confined between it and the convex area of the hole. When the control element is at the first location, gas will be filled in the primary space. At the second location, gas will be released. Gas will be stored temporarily in the primary space, so each time the volume of the released gas can be constantly maintained.
