Abstract

METODO DE OBTENCION CON AL MENOS DOS EYECTORES ACCIONADOS POR AIRE A PRESION DE UNA SUBPRESION DESEADA EN EL MENOR TIEMPO POSIBLE Y CON EL MENOR USO DE ENERGIA, INCLUYENDO ESTE METODO LA CONEXION DE LOS EYECTORES DE MODO QUE FUNCIONEN ALTERNATIVAMENTE SEGUN CUAL DE ELLOS RECIBA EL AIRE COMPRIMIDO. A SU VEZ, EL SUMINISTRO DE AIRE COMPRIMIDO SE CONTROLA EN RESPUESTA A LA SUBPRESION EN UNA CAMARA DE CAPTACION DE SUBPRESION COMUN A TODOS LOS EYECTORES. UN CONJUNTO DE EYECTORES (1) PARA EL METODO INCLUYE AL MENOS DOS EYECTORES ACCIONADOS POR AIRE A PRESION (2,3) CADA UNO CON SU PROPIA EFICACIA OPTIMA EN LOS MISMOS VALORES QUE EL AIRE COMPRIMIDO SUMINISTRADO. SE DISPONE UN SENSOR PARA DETECTAR LA SUBPRESION EN LA CAMARA (23) SUMINISTRANDO AIRE COMPRIMIDO A UN EYECTOR (2,3) ALTERNATIVAMENTE, SEGUN LA PRESION DETECTADA EN LA CAMARA (23). SE SUMINISTRA PRIMERO AIRE COMPRIMIDO AL EYECTOR (2) EVACUANDO LA MAYOR CANTIDAD DE AIRE POR UNIDAD DE TIEMPO, Y POR ULTIMO AL EYECTOR (3) GENERANDO LA SUBPRESIONMENOR.
