Abstract

"BOCAL DE INJEçãO DE FLUIDO E VáLVULA DE INJEçãO DE COMBUSTìVEL". Na extremidade jusante de combustível de um corpo de válvula (13), é arranjada uma placa de orifício de injeção (23) formada como um disco achatado. Na placa de orifício de injeção (25), são formados quatro orifícios de injeção (25a -25d) possuindo entradas de combustível em uma circunferência comum sobre o eixo central (27) da placa de orifício de injeção (25). Os orifícios de injeção (25a - 25d) são formados na direção de injeção de combustível à parte do eixo central (27) da placa de orifício de injeção (25). Em cada orifício de injeção, com respeito ao eixo de orifício de injeção (100) unindo o centro da entrada de combustível e o centro da saída de combustível de cada orifício de injeção (25a - 25d), a circunferência interna do orifício de injeção (101) mais distante do eixo central (27) da placa de orifício de injeção (25) é mais inclinada em direção à circunferência externa com respeito ao eixo central (27) do que a circunferência interna do orifício de injeção (101) menos distante do eixo central (27) da placa de orifício de injeção (25) com respeito ao eixo de orifício de injeção (100).
