Abstract
EN ESTA CLASE DE DISPOSITIVOS DE MANDO, LA VALVULA DE CONTROL DESCONECTA EL REGULADOR DE ENTRADA EN EL LIMITE DE PRESION O ELEVACION O LIMITA TAMBIEN LA CORRIENTE DE VOLUMEN APROVECHABLE. LA VALVULA DE CONTROL NO DIFERENCIA SI EL CONDUMIDOR SOBREPASA O QUEDA POR DEBAJO DEL LIMITE DE PRESION O ELEVACION, YA QUE TRABAJA INDEPENDIENTEMENTE DE LA DIRECCION DE TRABAJO DEL CONSUMIDOR. EL NUEVO DISPOSITIVO DE CONTROL DEBE CONTROLAR LOS CONSUMIDORES SEGUN LA DIRECCION. PARA UN CONTROL DEPENDIENTE DE LA DIRECCION DEL CONSUMIDOR (V), LA RAMIFICACION DE LA CONDUCCION DE MANDO (34) ESTA CONTINUAMENTE CONECTADO A LA VALVULA (51 - 55) A TRAVES DE LA CONDUCCION DE MANDO DE DESCARGA (36, 37, 38), CONECTANDOSE EN EL INTERIOR EXCLUSIVAMENTE EN UNA POSICION DE MANDO ( A O B) AL LADO DEL TANQUE, Y EN EL QUE EL CONSUMIDOR QUEDA EN DIRECCION A UN SOBREPASO DE UN LIMITE PREFIJADO DE PRESION O ELEVACION EN EL GRUPO DE CONSUMO. LA VALVULA DE CONTROL SALTA, PERO LA FUNCION DE DESCARGA O LIMITACION COMIENZA A TRABAJAR CUANDO LA VALVULA DE MANDO DE TRAYECTO LLEGA A UNA POSICION DE MANDO, EN LA CUAL EL CONSUMIDOR SE MOVERIA EN DIRECCION A SOBREPASAR AL LIMITE DE PRESION O ELEVACION. ESTE DISPOSITIVO DE MANDO, DADO SU CONTROL DEL CONSUMIDOR DEPENDIENTE DE LA DIRECCION, SIRVE, POR EJEMPLO, PARA DIRIGIR A LA VEZ DIFERENTES CILINDROS DE TRABAJO E HIDROMOTORES EN GRUAS MOVILES.
