Abstract

Se describe un sistema para mantener presión de cilindro de freno que comprende una válvula de mantenimiento, un tubo de freno, un depósito de emergencia y un cilindro de freno configurado para estar en comunicación fluida con el tubo de freno y el depósito de emergencia. El tubo de freno está configurado para mantener una presión predeterminada dentro del cilindro de freno durante la aplicación de freno en base en una diferencial entre una presión del depósito de emergencia y una presión del tubo de freno.A system for maintaining brake cylinder pressure is described comprising a maintenance valve, a brake tube, an emergency tank and a brake cylinder configured to be in fluid communication with the brake tube and the emergency tank. The brake tube is configured to maintain a predetermined pressure within the brake cylinder during brake application based on a differential between an emergency reservoir pressure and a brake tube pressure.
