Abstract
Amortiguador de vibraciones telescópico que consta de un cilindro de trabajo y un tubo envolvente que forma un recinto de compensación, estando prevista en el fondo del cilindro de trabajo una válvula de fondo. Se trata de obtener una válvula de fondo sencilla, que se pueda fabricar económicamente con los medios más sencillos y garantice un óptimo de libertad de diseño, pudiéndose fabricar la configuración de las aristas de control correcta y fácilmente. Para resolver este problema la válvula de fondo está configurada por al menos dos discos con vaciados correspondientes, formando los vaciados de ambos discos conjuntamente la unión para flujo de la válvula de fondo y estando unidos junto con discos de válvula correspondientes para formar una unidad constructiva. (Figura 1)
