Abstract

Изобретение относится к ячеистому монолитному элементу (1) для фильтрации частиц, отличающемуся тем, что периферические каналы (8), формирующие часть наружной стенки (7) названного элемента, конфигурированы для способствования формированию наружной стенки (7), внутренняя грань (7') которой является, по существу, плоской по всей длине элемента (1), причем плоская стенка также имеет увеличенную толщину (10, 10') в угловых изгибах (11), так что в поперечном сечении отношение R толщины Ее стенки, измеренной вдоль линии биссектрисы угла в угловом изгибе (11) элемента (1), к минимальной толщине Eназванной стенки составляет более чем 1,5.
