Piston for pneumatic spring essentially characterized by being constituted by a rod of stress, whose shank has a narrowed end zone that determines a step for the positioning of a washer and a piston, fixing these elements to the shank with the collaboration of the corresponding nut, it being provided that between said washer and the piston a recess is determined by an axial prolongation of the body of said piston, with the particularity that the piston has a smaller diameter than the internal diameter of the cylinder, establishing a perimetric conduction that communicates the two cylinder chambers, whose conduction is obturable by the segment itself when adapting on the piston body, so that this communication cooperates in a direction of displacement of the assembly, with a plurality of holes provided in the washer and with a single hole provided in the piston.
