Abstract

Sistema de frenos para tractor-remolque, accionados por presión de fluido, que se caracteriza porque tiene interconectados conductos de servicio y urgencia del tractor y remolque, frenos accionados por presión de fluido en el tractor y en el remolque, medios incluyendo una fuente de presión de fluido en el tractor, para suministrar presión de fluido a dichos conductos interconectados, para aplicar en servicio los frenos al tractor y remolque, al producirse un aumento de presión en dichos conductos interconectados de servicio y para aplicar en urgencia los frenos al tractor al producirse una disminución de presión en dichos conductos de urgencia interconectados, medios de válvula para controlar la comunicación a través de dichos conductos, compuesto de un cuerpo de cámara de control, cámaras de salida y de entrada de servicio, cámaras de salida y entrada de urgencia y boca de escape; dispuestas en serie y alineadas axialmente dichas cámaras de entrada y salida comunicando respectivamente con las dichas tuberías de servicio y urgencia del tractor y remolque y dicha boca de escape comunicando con la atmósfera, una válvula de urgencia dentro de dicha cámara de entrada de urgencia, un muelle actuando sobre dicha válvula de urgencia para normalmente cerrar la comunicación entre dichas cámaras de entrada y salida de urgencia, un pistón en dicha cavidad de control moviéndose hacia o lejos de dichas cámaras de entrada y salida, una pieza integrante con dicho pistón y entrante en dichas cámaras de salida y entrada de servicio, y terminando en dicha cámara de salida de urgencia, una válvula de servicio dentro de dicha cámara de entrada de servicio e íntegramente conectada a la parte de dicho pistón en dichas cámaras; un muelle actuando sobre dicho pistón obligándose a una posición en la que normalmente dicha válvula de servicio cierre la comunicación entre dichas cámaras de salida y entrada de servicio; la parte de dicho pistón en dicha cámara de salida de urgencia,cuando dichas válvulas están en posición de cierre, están separadas de dicha válvula de urgencia, pero pudiendo unirse con dicha válvula para abrirla cuando dicho pistón se mueve en la dirección de apertura de la válvula, un paso a través de dicha válvula de urgencia conectando normalmente dicha cámara de salida de urgencia y dicha boca de escape, cuando dichas válvulas están en su posición cerrada normal pero siendo cerradas por la parte de dicho pistón en dicha cámara de salida de urgencia cuando el dicho pistón se mueve en la dirección de apertura de la válvula.
