Abstract
Improved pneumatic piston, essentially characterized by having different piston walls coaxial to its axis that divide the cylinder chamber into several compartments, each having a pressure fluid inlet channel, and in one of the chambers a passage intended for to receive the fluid to retract the assembly, said shaft being completely isolated from the walls of the cylinder, isolating the different pistons by means of insulating fittings that surround them or using pistons of completely insulating material.
