The present invention provides a gas lifter comprising; a cylinder tube having its interior charged with a gas; and a rod mounted to be slid by the pressure of the gas in a state where the rod is inserted into the cylinder tube. A chamber part is positioned within the cylinder tube and has a space part formed therein. A plate blocking an inflow of the gas into the space part is mounted on the chamber part, the space part is separated from the inner space of the cylinder tube, and the plate is manufactured with a bimetal to allow opening/closing to be adjusted depending on the temperature of the gas. According to the present invention, the volume of gas to be charged is changed depending on the temperature, thereby maintaining the gas pressure. |
