Abstract
"FILTRO DE ELIMINAçãO DE GáS, VáLVULA DE RETENçãO, E, FILTRO DE PARTICULADO" Um sistema de eliminação de gás inclui um dispositivo de eliminação de gás (2) e um sistema de escorvamento (8). O dispositivo de eliminação de gás (2) inclui uma câmara de vórtice (14) que forma um vórtice no fluido que flui para a câmara (14) e um filtro de particulado (30) que remove partículas do fluido. O filtro de particulado (30) é posicionado na câmara de vórtice (14), de modo que o vórtice é formado em um volume substancial da câmara (14) antes de encontrar o filtro de particulado (30). Quando fluido encontra o filtro de particulado (30), o vórtice é geralmente paralisado, e adicionais gases liberados ascendem através do topo aberto do filtro de particulado (30). O dispositivo (2) também inclui uma câmara de saída (36) conectada à câmara de vórtice (14), e o filtro de particulado (30) se estende para o interior da câmara de saída (36). Uma válvula de retenção (38) é posicionada na saída (40) da câmara de saída (36) para bloquear fluxo quando o dispositivo (2) contém excesso de gás. O sistema de escorvamento na forma de um bloco de almofada (8) é disposto para forçar ar ou fluido para cima, para desalojar a válvula de retenção (38), caso ela fique emperrada na sede de válvula (42).
