Abstract

Un dispositivo de amortiguamiento de vagón de ferrocarril tiene un cilindro hidráulico que contiene fluido presurizado. El cilindro tiene un cuerpo cilíndrico con una cámara interior y una cámara de depósito. Un pistón se coloca de manera móvil en la cámara interior. El cuerpo cilíndrico tiene una abertura de purgado que permite el flujo de purgado desde la cámara interior hasta la cámara de depósito. La válvula de orificio de purgado en la abertura de purgado tiene un alojamiento de válvula y un husillo recibido en el alojamiento de válvula que se mueve para permitir y restringir el flujo de fluido a través de una trayectoria de flujo de purgado basándose en la presión del fluido. El husillo tiene un canal de orificio que permite un flujo de fluido restringido a través del alojamiento de válvula cuando la presión en la cámara interior es mayor que la presión en la cámara de depósito.
