Abstract

"VáLVULA EGR SOLENóIDE EQUILIBRADA TIPO SANFONA".Um conjunto de válvula tipo sanfona (11) que inclui um corpo deválvula (13), um alojamento sanfona (39) e um atuador de válvula(15). O corpo da válvula (13) inclui uma entrada (17), uma saída(19) e uma base de válvula (29). Um elemento de fecho de válvula(25) estando engatável com a base da válvula (29) para controlar ofluxo de fluido. O elemento de fecho de válvula (25) possui umahaste (27) que tem uma parte superior (27b) tendo um diâmetromédio pelo menos 25% menor do que o diâmetro da parte inferior(27a). Um conjunto sanfona de equilibrio de pressao (61) divide oalojamento sanfona (39) em uma primeira câmara (69) conectadapor uma primeira via de passagem (67) à passagem do fluido àjusante da base (29) e uma segunda câmara (55) conectada poruma via de passagem (65) à passagem do fluido à montante dabase da válvula (29).
