Abstract
LA CONTERA INFERIOR (1) LLEVA UNA PLACA ADAPTADORA (2) DE FORMA CUADRADA ATRAVESADA POR ABERTURAS DE PASO DE AGUA (8, 9) Y UNA PLACA DE FILTRACION (11) PERFORADA DE AGUJEROS DE PEQUEÑAS DIMENSIONES UNIDA A LA PLACA ADAPTADORA (2). LAS ABERTURAS DE PASO DE AGUA (8, 9) DE LA PLACA ADAPTADORA ESTAN DISPUESTAS DE MANERA TOTALMENTE SIMETRICA RESPECTO DE LAS MEDIANAS (6, 6'') Y RESPECTO DE LAS DIAGONALES (5, 5'') DE LA PLACA ADAPTADORA. EL CONJUNTO DE ABERTURAS (8, 9) EN CADA ZONA DE LA PLACA ADAPTADORA LIMITADA POR UNA DIAGONAL Y UNA MEDIANA LLEVA ABERTURAS (8) QUE TIENEN UNA SECCION TRANSVERSAL DE FORMA OBLONGA Y EVENTUALMENTE ABERTURAS DE PASO DE AGUA (9) DE OTRA FORMA. LA PLACA DE FILTRACION (11) LLEVA CONJUNTOS DE AGUJEROS (15) DE PEQUEÑAS DIMENSIONES DISPUESTOS EN LAS ZONAS DE LA PLACA (11) QUE COINCIDE CON LAS ABERTURAS OBLONGAS (8) DE LA PLACA ADAPTADORA (2).
