Abstract

Dispositivo cilindro-pistón a gas (10) que comprende un cuerpo (1) como estructura, y un vástago-pistón (2) que se desplaza en el interior del citado cuerpo (1), estando el interior del cuerpo (1) ocupado por un gas compresible, comprendiendo el dispositivo (10) además un casquillo (20) entre el cuerpo (1) y el vástago-pistón (2), tal que el citado casquillo (20) comprende una zona deformable (40) la cual contiene a su vez una junta tórica (3) de unión que une a estanqueidad el casquillo (20) con la cara interna del cuerpo (1), estando dicha zona deformable (40) diseñada de manera que, al deformarse, hace que la junta tórica (3) deje de ser estanca en la unión del casquillo (20) con la cara interna del cuerpo (1).
