Abstract

ESTA PROVISTA CON UN ALOJAMIENTO DE BOMBA (1) QUE INCLUYE UNA CAMARA DE SUCCION (14) Y UNA CAMARA DE PRESION (9), DEL TIPO QUE INCLUYE UN SISTEMA DE AUTOCEBADO DE VALVULA AUTOMATICA. LA VALVULA AUTOMATICA MENCIONADA ESTA FORMADA POR UNA LAMINA FLOTANTE (7), FLEXIBLE Y ELASTICA, QUE MIRA HACIA UN ASIENTO DE VALVULA (10) QUE PUEDE SER CERRADO POR LA LAMINA FLOTANTE CUANDO AUMENTA LA PRESION EN LA CAMARA DE PRESION. LA LAMINA SE MANTIENE EN UNA POSICION ESENCIALMENTE VERTICAL, ADYACENTE A DOS SALIENTES PARALELOS (22) SITUADAS A CADA LADO DEL ASIENTO DE VALVULA, CON DOS PASADORES (11) QUE PASAN CON LIBRE JUEGO A TRAVES DE LOS ORIFICIOS ALARGADOS CORRESPONDIENTES (12) REALIZADOS EN LA LAMINA. EL CIERRE DEL ORIFICIO ES IMPLEMENTADO MEDIANTE LA FLEXION DE LA LAMINA (7) APOYADA EN DICHAS VARILLAS PARALELAS, Y LA APLICACION POSTERIOR DE LA LAMINA ARQUEADA EN EL ASIENTO DE VALVULA.
