Abstract

Patente de Invenção: <B>"VáLVULA INJETORA DE COMBUSTìVEL"<D>. A invenção refere-se a válvula injetora de combustível, que possui uma agulha de válvula (13) axialmente móvel, que abrange ao menos um suporte de corpo de fechamento (17) e um corpo de fechamento de válvula (18) esférico. O corpo de fechamento de válvula (17) aloja com uma região extrema (46) a jusante o corpo de fechamento de válvula (18). O corpo de fechamento de válvula (18) coopera com uma sede de válvula (15) de um corpo de sede de válvula (14). A montante da sede de válvula (15) tem o corpo de sede de válvula (14) regiões de material (51) e reentrâncias de material (52) alternando-se por sua periferia, enquanto que a região extrema (46) do suporte de corpo de fechamento (17) é formada igualmente com segmentos de material (50) e regiões de abertura (49) alternando-se pela periferia. Os segmentos de material (50) projetam-se então para dentro das reentrâncias de material (52) bem como as regiões de material (52) para dentro das regiões de abertura (49). A válvula injetora de combustível é apropriada especialmente para o emprego em instalações de injeção de combustível de máquinas de combustão interna de ignição estranha, compressoras de mistura.Invention Patent: <B> "FUEL INJECTION VALVE" <D>. The invention relates to the fuel injection valve, which has an axially movable valve needle (13), which comprises at least one closing body support (17) and a spherical valve closing body (18). The valve closing body (17) houses an end region (46) downstream of the valve closing body (18). The valve closing body (18) cooperates with a valve seat (15) of a valve seat body (14). Upstream of the valve seat (15) has the valve seat body (14) material regions (51) and material recesses (52) alternating through its periphery, while the extreme region (46) of the closing body (17) is also formed with material segments (50) and opening regions (49) alternating through the periphery. The material segments (50) then project into the material recesses (52) as well as the material regions (52) into the opening regions (49). The fuel injection valve is especially suitable for use in fuel injection installations for internal combustion machines with strange ignition, mixing compressors.
