Abstract
A turn-back coaxial gas pressurizing pump and gas pressurizing method using the same, relate to the field of gas pressure boosting. The turn-back coaxial gas pressurizing pump includes a primary cylinder, a primary piston, a secondary cylinder serving as a rod of the primary piston, a pressure bar, an air pump bonnet, a secondary piston and a piston rod. The primary cylinder, the secondary cylinder and the piston rod are arranged coaxially. A rear end of the piston rod extends through a first non-returning adaptive valve provided in the primary piston and is fixed on the bottom wall of the primary cylinder. As a result, the two pistons move in opposite directions to boost the pressure.
