Abstract
UN SISTEMA HIDRAULICO (1) PARA CONTROLAR LA ROTACION DE UNA ESTRUCTURA DE VAGON DE TREN (2), Y QUE PRESENTA UN CONJUNTO DE BOMBA DE MOTOR (8) CONECTADO A UN DEPOSITO DE LIQUIDO HIDRAULICO (7) Y A UNA LINEA DE ABASTECIMIENTO (14); UN NUMERO DE ACTUADORES HIDRAULICOS (3A, 3B, 4A, 4B) PARA EJERCER FUERZA MECANICA EN LA ESTRUCTURA (2) PARA GIRARLA; UNA VALVULA DE SOLENOIDE (26) PARA CONECTAR SELECTIVAMENTE LOS ACTUADORES HIDRAULICOS (3A, 3B, 4A, 4B) A LA LINEA DE ABASTECIMIENTO (14) O PARA UN DRENAJE (29) EN RESPUESTA A LAS SEÑALES DE CONTROL ELECTRICAS; Y UNA VALVULA DE INICIO DE DESVIO (64) PARA DESPRESURIZAR LA LINEA DE ABASTECIMIENTO (14) DURANTE EL ARRANQUE DEL CONJUNTO DE LA BOMBA DE MOTOR (8); LA VALVULA DE INICIO DE DESVIO (64) SIENDO UNICAMENTE OPERADA HIDRAULICAMENTE, UNA VALVULA NORMALMENTE ABIERTA, QUE SE CONMUTA AUTOMATICAMENTE CUANDO EL ABASTECIMIENTO DEL CONJUNTO DE LA BOMBA DE MOTOR (8) ALCANZA UN VALOR DE UMBRAL PREDETERMINADO.A HYDRAULIC SYSTEM (1) TO CONTROL THE ROTATION OF A TRAIN WAGON STRUCTURE (2), AND WHICH PRESENTS AN ENGINE PUMP ASSEMBLY (8) CONNECTED TO A HYDRAULIC LIQUID TANK (7) AND A SUPPLY LINE (14 ); A NUMBER OF HYDRAULIC ACTUATORS (3A, 3B, 4A, 4B) TO EXERCISE MECHANICAL FORCE IN THE STRUCTURE (2) TO TURN IT; A SOLENOID VALVE (26) TO SELECTLY CONNECT THE HYDRAULIC ACTUATORS (3A, 3B, 4A, 4B) TO THE SUPPLY LINE (14) OR FOR A DRAIN (29) IN RESPONSE TO ELECTRICAL CONTROL SIGNALS; AND A BYPASS START VALVE (64) TO DEPRESSURIZE THE SUPPLY LINE (14) DURING STARTING THE ENGINE PUMP ASSEMBLY (8); THE BYPASS START VALVE (64) BEING SOLELY OPERATED HYDRAULICALLY, A NORMALLY OPEN VALVE, WHICH SWITCHES AUTOMATICALLY WHEN THE SUPPLY OF THE ENGINE PUMP ASSEMBLY (8) REACHES A PREDUM THRESHOLD VALUE.
