Abstract
Embolo para una disposición émbolo-cilindro, en particular un émbolo de amortiguador, con un cuerpo de émbolo (6), el cual está dotado sobre su superficie de circulación, en una zona colindante con un extremo del émbolo (4.1), con por lo menos un alma (12) circular, que sobresale la superficie perimétrica, a la cual se conectan, extendiéndose en dirección hacia el otro extremo del émbolo (5.1), unas almas de apoyo (10) que discurren longitudinalmente dispuestas paralelas a distancia unas junto a otras, limitando en cada caso dos almas de apoyo (10) contiguas una escotadura (11) en forma de ranura, las cuales están abiertas en dirección longitudinal por sus extremos opuestos al alma circular (12), y con una obturación (9) en forma de manguito de un material de obturación deformable en caliente, que está formada de tal manera sobre el cuerpo del émbolo (6) que tanto el alma circular (12) como también las almas de apoyo (10) están formadas al menos a lo largo de una parte de su altura en el material de la obturación (9) en forma de manguito, caracterizado porque las almas de apoyo (10) que discurren longitudinalmente discurren sobre la superficie perimétrica, junto al cuerpo del émbolo (6), formando un ángulo con respecto a la caña del amortiguador (14).
