Abstract

"ARMAçãO PARA ELEMENTO FILTRANTE DE LìQUIDOS E FILTRO PARA LìQUIDOS". Uma armação para elemento filtrante de líquido (7) é apresentada que consiste em um corpo moldado por injeção alongado, convenientemente composto de uma série de unidades moldadas por injeção colineares (13); A armação tem uma pluralidade de nervuras de suporte (14) se irradiando de um eixo geométrico central da mesma e um colar de suporte (17) circundando as bordas externas das nervuras na extremidade operativamente superior. O colar tem formado solidariamente com o mesmo uma pluralidade de trilhos de suporte (18) dirigidos radialmente para dentro tendo extremidades internas cooperantes com o corpo moldado entre suas nervuras de suporte adjacentes. De preferência, o colar tem um número de trilhos de suporte voltados para dentro igual ao número de nervuras de suporte radialmente dispostas com as bordas internas (19) dos trilhos de suporte sendo recebidas perfeitamente em uma esquina formada entre cada par de nervuras de suporte adjacentes. A invenção também proporciona um filtro para liquido incluindo elementos filtrantes dotados de armações deste tipo.
