Abstract

"FILTRO DE FLUXO ABERTO COM ELEMENTO DE SEGURANçA". Um filtro de fluido de fluxo aberto tem um elemento de filtragem principal enrugada tendo uma pluralidade de rugas em um laço fechado tendo um perímetro externo definido por uma pluralidade de pontas de rugas externas, e um perímetro interno definido por uma pluralidade de pontas de rugas internas. O laço tem um interior oco que se estende ao longo de um eixo. O fluido a ser filtrado flui através do elemento de filtragem principal de um lado sujo fluxo acima para um lado limpo fluxo abaixo, e flui axialmente no interior oco. O elemento de filtragem principal tem uma passagem de fluxo axial que se estende ao longo do eixo e que circunscreve o interior oco e tem um perímetro de fluxo maior do que o perímetro interno. Um elemento de filtragem de segurança fluxo abaixo do elemento de filtragem principal filtra tanto o fluxo axial no interior oco como o fluxo adicional entre o perímetro de fluxo e o perímetro interno. Um filtro com fluxo adicional também é fornecido.
