Abstract

UN APARATO DE DIRECCION DE ENERGIA HIDRAULICA, QUE TIENE MANGUITO (54) DE VALVULA CONVENCIONAL, RELATIVAMENTE ROTATORIO, Y CUERPO (64) DE VALVULA PARA LA REGULACION DEL FLUJO; UN ELEMENTO (90), MECANICAMENTE ELASTICO, PARA ACTIVAR UNA FUERZA MECANICA DE CENTRAR, EN RELACION A LA ROTACION RELATIVA DEL MANGUITO DE VALVULA Y CUERPO DE VALVULA, QUE TIENDE A REPONER EL MANGUITO DE VALVULA Y EL CUERPO DE VALVULA EN UNA POSICION CENTRADA; Y UN MECANISMO ELECTROMAGNETICO INTEGRAL (92), QUE SE OPONE VARIABLEMENTE A LA FUERZA DE CENTRADO MECANICA, PARA AJUSTAR EL NIVEL DE LA ENTRADA DE DIRECCION DEL OPERADOR QUE SE REQUIERE PARA CREAR UN NIVEL DADO DE AYUDA POR SERVOMANDO. EL MECANISMO ELECTROMAGNETICO COMPRENDE UNA BOBINA DEL CAMPO INDUCTOR (130) Y UN PAR DE ELEMENTOS DE CONDUCCION DE FLUJO (106, 108), SUSTENTADOS PARA ROTACION CON EL MANGUITO DE VALVULA Y EL CUERPO DE VALVULA, RESPECTIVAMENTE. LOS ELEMENTOS DE CONDUCCION DE FLUJO TIENEN DIENTES (112, 114) INTERCONECTADOS, QUE ESTAN MAGNETICAMENTE ACOPLADOS A LA BOBINA DEL CAMPO INDUCTOR, PARA DEFINIR UN CIRCUITO MAGNETICO QUE TIENE UN ESPACIO DE AIRE DE TRABAJO ENTRE LOS DIENTES, QUE VARIA CON LA ROTACION RELATIVA DEL MANGUITO DE VALVULA Y DEL CUERPO DE VALVULA.
