Abstract

ESTE PROCESO DE OPERACION DE UN ACCIONAMIENTO DE REGULADOR HIDRAULICO (2) CON SEÑAL DE AJUSTE PROPORCIONAL A LA PRESION ESTA PROVISTO DE UN AMPLIFICADOR (33) PARA SEÑALES ELECTRICAS, CON AL MENOS UN TRANSMISOR (24) ELECTROHIDRAULICO CONECTADO EN SERIE AL ACCIONAMIENTO DEL REGULADOR HIDRAULICO, Y CON UN AMPLIFICADOR DE DESCARGA HIDRAULICO CONECTADO ENTRE EL ACCIONAMIENTO DE REGULADOR (2) Y EL TRANSMISOR ELECTROHIDRAULICO (24). SE TRATA DE UN PROCESO DE OPERACION DE UN ACCIONAMIENTO DE REGULADOR HIDRAULICO CON SEÑAL DE AJUSTE PROPORCIONAL A LA PRESION, QUE ES FACIL Y BARATO DE PRODUCIR. ESTO SE CONSIGUE COLOCANDO ENTRE EL AMPLIFICADOR DE DESCARGA HIDRAULICO Y EL ACCIONAMIENTO DEL REGULADOR UN EMBOLO CILINDRICO FUNCIONANDO COMO TRANSMISOR.
