Abstract

Amortiguador hidráulico, para colocación en el fondo de un eje de ascensor para desacelerar un vehiculo ascensor, caracterizado porque incluye: Un recipiente de líquido un cilindro de pistón en el interior de dicho recipiente, definiendo dicho cilindro dos cámaras de líquido en el recipiente, una en el interior del cilindro y la segunda alrededor del cilindro, conteniendo también dicho cilindro unos orificios entre las dos cámaras; un pistón para contactar el fondo de un vehículo ascensor y aplicar fuerza desaceleradora al vehículo cuando desciende, extendiéndose dicho pistón a través de un manguito en la parte superior del recipiente en el interior de dicho cilindro de pistón, estando situado dicho manguito en la parte superior que dicho cilindro de pistón, existiendo un espacio entre el pistón y el manguito para la circula un dispositivo de tobera para permitir que la mezcla de líquido/aire pase desde dicha segunda cámara hasta la parte superior de dicho cilindro de pistón, para una expansión volumétrica de la mezcla a través de dicha tobera y para dirigir hacia. el pistón mientras se desplaza en el cilindro de pistón, el líquido que se condensa a partir de dicha mezcla a su paso por la tobera; existiendo el correspondiente dispositivo de resorte para resistir la extensión del pistón dentro del recipiente y extenderla fuera del recipiente cuando el pistón no es contactado por el vehículo.
