Abstract

EL SISTEMA SUMINISTRA UNA COMPENSACION CONTINUA DEL VOLUMEN DISPENSADO EN UN SISTEMA DE CONTROL DE FLUJO REGULADO POR PRESION PARA COMPENSAR LOS CAMBIOS EN LA VISCOSIDAD DEL MATERIAL Y EL DESGASTE EN LOS COMPONENTES. SE PREAJUSTAN DOS CONTADORES CON UN VALOR PREDETERMINADO. EL PRIMER CONTADOR (11) ES DECREMENTADO POR LOS IMPULSOS DE UN MEDIDOR DE FLUJO EN LA SALIDA DEL SISTEMA MIENTRAS QUE EL SEGUNDO CONTADOR (18) SE DECREMENTA DE ACUERDO CON EL COMANDO DE ENTRADA. CUANDO EL PRIMER CONTADOR ALCANZA EL CERO, LOS CONTENIDOS DEL SEGUNDO CONTADOR SON EXAMINADOS Y LA GANANCIA SE INCREMENTA O SE DECREMENTA DE FORMA CONCORDANTE.
