Abstract

ESTE ACCIONAMIENTO PARA UNA VALVULA REGULADORA DE VAPOR (2) MUESTRA UNA DISPOSICION DE VALVULA CONTROL SOBRE LA REGULACION DE LA PRESION DE ACCIONAMIENTO DE UN ACCIONAMIENTO REGULADOR (1). DEBE SER CONSEGUIDO UN ACCIONAMIENTO PARA UNA VALVULA DE REGULACION DE VAPOR QUE TAMBIEN PUEDA SER ACCIONADA DE FORMA RAPIDA Y SEGURA CON VALORES DE PRESION DE ACEITE COMPARATIVAMENTE ALTOS. ESTO SE CONSIGUE A TRAVES DE LA DISPOSICION CON VALVULA CONTROL QUE AL MENOS DISPONE DE DOS VALVULAS DE MANDO (17, 21) REGULABLES, QUE PUEDEN SER ACCIONADAS A PRESION SOBRE UNA VALVULA DE MANDO PREVIO (VALVULA DE PRESION PROPORCIONAL 24, 34).
