Abstract

Amortiguador de vibraciones, que comprende un tubo a presión, en el que va conducido un émbolo unido a un vástago de émbolo axialmente móvil, por medio de una guía del vástago de émbolo, que cierra el tubo a presión, en donde el émbolo subdivide al tubo a presión relleno de medio amortiguador en dos cámaras de trabajo; con un segmento de émbolo, que cubre una superficie perimetral del émbolo y que presenta una sección transversal, prácticamente, en forma de U con unas superficies de sujeción, apoyándose las superficies de apoyo en las caras superior e Inferior del émbolo, caracterizado porque en, por lo menos, una cara del émbolo, al menos, una parte del émbolo, en la que atacan las superficies de sujeción del segmento de émbolo, presenta una superficie perfilada, de modo que la distancia entre una cara del émbolo y un plano de referencia imaginario, que discurre paralelamente a la cara del émbolo, no alcance u sobrepase, alternativamente, una medida de ajuste prevista.
