Abstract
Embolo para una disposición émbolocilindro, en particular un émbolo de amortiguador, con un cuerpo de émbolo (6), el cual está dotado sobre su superficie de circulación con por lo menos dos almas (10) circulares, que limitan una ranura (11), caracterizado porque sobre las almas está formada una obturación (9) en forma de manguito realizada en un material plástico deformable en caliente, que solapa las almas (10), y que presenta canales de paso (7, 8) axiales en el cuerpo del émbolo, los cuales están cerrados mediante válvulas de estrangulación (7.1, 8.1) que se abren unilateralmente, así como por lo menos una abertura radial (12), que conecta por lo menos un canal de paso (7, 8) con la ranura (11) entre dos almas (10).
