Energy saving oil and gas cylinder

Disclosed is an energy saving oil and gas cylinder utilizing the properties of repulsion and inadhesion of fluoroplastic and glue molecule, and the output work of the energy saving oil and gas cylinder more approaches to the input work of the energy saving oil and gas cylinder. The utility model has the improved technical proposal that the inner wall of a piston barrel and the outer wall of a piston rod are respectively added with a layer of polytetrafluoroethylene bushing; gaps between a piston barrel sleeve and a piston, and between a piston rod sleeve and the inner wall of the outlet of a barrel lid are blocked fully with self-adhesive liquid cement which is stuck and connected with metal and moves with the metal, but the self-adhesive liquid cement is in the fluid state with the fluoroplastic. The utility model has the advantages of low friction and energy-saving.
