Abstract

Sistema de amortiguación para su uso con un actuador (20) de puerta de cilindro neumático/motor diferencial para impulsar una puerta entre posiciones abierta y cerrada, en el que dicho motor diferencial incluye un cilindro (22) grande alineado con un cilindro (24) pequeño y un par de pistones (28, 30) asociados que tienen un conjunto de cremallera (32) y piñón (34) conectado entre y controlado mediante el movimiento de dichos pistones asociados, caracterizado porque dicho sistema de amortiguación comprende: (a) una tapa (38) grande para sellar dicho cilindro grande; (b) una corredera (50) que se extiende desde dicha tapa grande y al interior de dicho cilindro grande, estando dicha corredera en contacto de fluido con una parte interior de dicho cilindro grande; (c) al menos un primer conducto (60) que tiene un primer diámetro que se extiende a través de una primera parte (52, 54) de pared de dicha corredera; (d) al menos un segundo conducto (62) que tiene un segundo diámetro menor que dicho primer diámetro y que se extiende a través de una segunda parte (52, 54) de pared de dicha corredera, estando dicha segunda parte de pared lateral en una ubicación alejada de dicha primera parte de pared lateral; (e) una válvula asociada con dicha corredera para aplicar fluido a través de dichos conductos primero y segundo al interior de dicho cilindro grande durante un ciclo de cierre de puerta y dejar que escape fluido a través de dichos conductos primero y segundo desde el interior de dicho cilindro grande durante un ciclo de apertura de puerta; (f) un dispositivo (64) de cierre para sellar dicha corredera cerca del final de un ciclo de apertura de puerta, impidiendo el flujo de escape a través de dicho primer conducto de modo que el flujo de escape se produce a través del segundo conducto y ralentizando el movimiento de avance de dicho par de pistones; (g) un sistema (65) de desviación para montar dicho dispositivo de cierre con respecto a dicha tapa grande y dicha corredera, estando dicho sistema de desviación adaptado para mover linealmente dicho dispositivo de cierre con respecto a dicha tapa grande y dicha corredera; y (h) un dispositivo (72) de ajuste para ajustar la extensión lineal de dicha corredera al interior de dicho cilindro grande y ajustar la distancia entre dicho dispositivo de cierre y dicha corredera para uno de aumentar y disminuir la cantidad de tiempo antes de que se produzca el sellado de la corredera para ajustar el momento en el que se produce la amortiguación durante el ciclo de apertura de puerta.
