Abstract
CONSTA DE UNA APERTURA DE DIAFRAGMA REGULABLE HIDRAULICAMENTE ENTRE UNA CONDUCCION DE ENTRADA Y UNA DE SALIDA (4,5) CON UNA VALVULA DE MANDO TRIDIMENSIONAL (20) CONECTADA CON UN MANDO DE AJUSTE EXTERNO QUE, EN LA PARTE DE ENTRADA (16) Y CON SU CIERRE DE MANDO, ESTA ENCERRADO EN EL DIAFRAGMA (1), DE TAL MODO QUE SU ELEMENTO DE DIAFRAGMA SE IMPULSA EN OPOSICION A LA PRESION EN LA CONDUCCION DE SALIDA (5) Y LA FUERZA DE UN RESORTE (9). EN LOS DISPOSITIVOS DE MANDO CONOCIDOS ES NECESARIO, PARA LA INFORMACION DE POSICION DEL ELEMENTO DE DIAFRAGMA, UN REGISTRADOR INDUCTIVO DE RECORRIDO QUE GOBIERNA EL ELEMENTO DE MANDO PARA QUE ESTE VARIE LA FUERZA DE AJUSTE PARA MANTENER EL TAMAÑO DE APERTURA DEL DIAFRAGMA. ESTO CONLLEVA GRANDES GASTOS. TAMBIEN ES UNA DESVENTAJA EL QUE LA VALVULA DE MANDO DEBE TOMAR TODA LA PRESION DE TRABAJO Y DEBE SER PRECISA Y CARA. SEGUN EL INVENTO, SE PREVE QUE LA SEGUNDA SALIDA DE LA VALVULA DE MANDO TRIDIMENSIONAL (20) ESTE CONECTADA CON LA CONDUCCION DE SALIDA (5) DE FORMA QUE EL ELEMENTO DE VALVULA DE LA VALVULA DE MANDO (20) SE IMPULSA CONTRA LA FUERZA DE AJUSTE DE LA PRESION EN EL CIERRE DE MANDO Y SE OPONE A LA PRESION EN LA SEGUNDA SALIDA, Y DE FORMA QUE LA PRESION DE ENTRADA A LA VALVULA DE MANDO, EN AL MENOS LA MAXIMA DIFERENCIA DE PRESION POSIBLE DE LA VALVULA DE MANDO, ES MAYOR QUE LA DE LA PRESION DE SALIDA.
