Abstract

EL INVENTO SE REFIERE A UN CONTROL HIDRAULICO PARA UN MECANISMO DE ELEVACION, CON UNA TUBERIA DE PRESION DE TRABAJO, LA QUE CONTIENE UNA VALVULA DE RETENCION Y CONECTA UNA FUENTE DE PRESION CON UN HIDROMOTOR. DE ESTA TUBERIA DE PRESION DE TRABAJO SE DESVIA UNA TUBERIA DE "CIRCUNVALACION" (BEIPABLEITUNG) HACIA EL DEPOSITO. ADEMAS DISPONE DE UN REGULADOR DE CORRIENTE DE TRES VIAS Y DE UN REGULADOR DE CORRIENTE DE DOS VIAS, CADA UNO CON MANIPULACION POR UN IMAN PROPORCIONAL. CADA UNO DE LOS REGULADORES DE CORRIENTE DISPONE DE UNA BALANZA DE PRESION CON UN PISTON DE REGULACION Y UN DIAFRAGMA DE MEDICION QUE SE ACTIVARA A TRAVES DEL IMAN PROPORCIONAL. LOS MECANISMOS DE CONTROL CONOCIDOS HASTA AHORA PRECISAN UN DIAFRAGMA DE MEDICION Y UN IMAN PROPORCIONAL PARA CADA REGULADOR DE CORRIENTE, LO QUE CAUSA UNOS GASTOS DE CONSTRUCCION Y CONTROL ADICONALES. SIN EMBARGO, EL INVENTO HA PREVISTO UN DIAFRAGMA DE MEDICION COMUN CON UN SOLO IMAN PROPORCIONAL PARQ AMBAS BALANZAS DE PRESION, LO QUE REDUCIRA CONSIDERABLEMENTE LOS GASTOS DE CONSTRUCCION Y CONTROL.
