Abstract

UN SISTEMA DE RETROEXPULSION DE FILTRO (10) QUE INCLUYE UN PISTON NEUMATICAMENTE DIRIGIDO (16) O UN ACUMULADOR NEUMATICO PARA PROPULSAR UN SUMINISTRO DE UN FLUIDO DE RETROEXPULSION FILTRADO, CONTENIDO EN UNA CAMARA DE FLUIDO DE RETROEXPULSION (34), EN UNA DIRECCION OPUESTA A TRAVES DE UN ELEMENTO DE FILTRO (14). EL SISTEMA (10) PROPORCIONA UNA PRESION CONSTANTE DE ALTA INTENSIDAD Y SUSTANCIALMENTE INSTANTANEA DE UN FLUJO DE RETROEXPULSION QUE ELIMINA EFICAZMENTE LA OBTURACION POR CONTAMINANTES DE UN ELEMENTO DE FILTRO (14).
