Abstract

EL INVENTO SE REFIERE A UN METODO Y A UN DISPOSITIVO PARA UBICAR CORRECTAMENTE EL PISTON DE UN DISPOSITIVO DE CILINDRO DE FLUIDO A PRESION QUE TRANSPORTA CARGA, EN EL QUE EL FLUIDO ES UN GAS COMPRIMIBLE Y EL DISPOSITIVO DE CILINDRO ES DE DOBLE ACCION. UNA PRESION DE FUNCIONAMIENTO VARIABLE (P1) ACTUA SOBRE UN LADO DEL PISTON (2) Y UNA PRESION APLICADA DE VALOR CONSTANTE (P2) ACTUA SOBRE EL OTRO LADO DEL MISMO. AMBAS PRESIONES (P1,P2) PUEDEN ALIGERARSE ALTERNATIVAMENTE POR EVACUACION, POR EL MOVIMIENTO DEL PISTON EN EL DISPOSITIVO DE CILINDRO (1). EL INVENTO SE CARACTERIZA POR UN REGULADOR DE PRESION (12) QUE DETECTA LA CARGA QUE ACTUA EN EL DISPOSITIVO DE CILINDRO (1) DE UNA CARGA EXTERNA (F) Y QUE INCLUYE UNA CAMARA DE PRESION (12'') CON UNA PARED MOVIL (13,13'') QUE SOPORTA EL DISPOSITIVO DE CILINDRO (1) Y EN LA QUE LA PRESION EN FUNCIONAMIENTO (PI) SE APLICA MEDIANTE UNA VALVULA (17,18) CUYOS MOVIMIENTOS DE APERTURA Y CIERRE ESTAN DETERMINADOS POR LOS MOVIMIENTOS DE LA PARED MOVIL (13,13'').
