Abstract

VALVULA DE MANDO DE PRESION PARA GOBERNAR LA PRESION DE FRENADO EN DEPENDENCIA DEL DESGASTE DE LAS GUARNICIONES, CON LA QUE SE DEBE RETENER, CON MEDIOS SENCILLOS LA PRESION DE FRENADO EN LOS FRENOS DE RUEDA (15, 16) CUANDO SENSORES DE DESGASTE (18, 19) DETECTEN DESGASTE EXCESIVO EN LAS GUARNICIONES DE FRENO (20, 21). ENTRE UNA VALVULA DE FRENO DE SERVICIO (12) Y LOS CILINDROS DE FRENO DE RUEDA (13, 14) ESTAN PREVISTAS EN LA TUBERIA DE FRENO (17) UNA VALVULA DE MANDO DE PRESION (23.1) CON UN ELEMENTO DE CIERRE CONMUTABLE GOBERNADO PREVIAMENTE, PARA BLOQUEAR LA TUBERIA DE FRENO, Y UNA VALVULA ANTIRETORNO (33) DISPUESTA EN PARALELO, SOLICITADA POR MUELLE, CON PASO A LOS CILINDROS DE FRENO DE RUEDA (13, 14). CUANDO ESTA BLOQUEADA LA TUBERIA DE FRENO SE PROVOCA EN LA VALVULA ANTIRETORNO (33) UNA DISMINUCION DE LA PRESION DE FRENO INTRODUCIDA CON LA VALVULA DE FRENO DE SERVICIO (12).
