Abstract

"DISPOSIçãO DE FILTRO DE LìQUIDO COM FILTRO SECUNDáRIO E FLUXO DE ULTRAPASSAGEM". Disposições de filtragem de líquido são fornecidas. Em geral, as disposições de filtragem de líquido compreendem um alojamento, um elemento de filtro primário, uma construção de filtro secundário e uma disposição de válvula de ultrapassagem. os componentes são dispostos de forma que durante a operação normal, o líquido flua através do elemento de filtro primário e então através da construção de filtro secundário; e, de forma que durante as operações de válvula de ultrapassagem, o fluxo circunde o elemento de filtro primário e seja direcionado através da construção de filtro secundário, antes de deixar a disposição de filtro de líquido. Ambas uma modalidade rotativa descartável e uma modalidade de cartucho que pode ser servido são fornecidas.
