Abstract

"DISPOSITIVO INJETOR DE COMBUSTìVEL E SISTEMA DE COMBUSTìVEL PARA MOTORES DE COMBUSTãO INTERNA, BEM COMO MOTOR DE COMBUSTãO INTERNA". Um dispositivo injetor de combustível (10) para motores de combustão interna abrange uma caixa (12) estirada ao comprido com uma extremidade de injeção (28). Na caixa (12) se estende em sua direção longitudinal uma reentrância (34). Esta é ligável com uma entrada de combustível (20). Ao menos duas aberturas de saída (30, 32) distanciadas axialmente entre si estão presentes na extremidade de injeção (28). Ao menos dois elementos de válvula (40, 42) coaxiais e axialmente móveis estão dispostos ao menos parcialmente na reentrância (34). Eles cooperam com sedes de válvula na região das aberturas de saída (30, 32). Para se poder construir o dispositivo injetor de combustível (10) tão simples e pequeno quanto possível, se propõe que os elementos de válvula (40, 42) apresentem uma ligação de arraste (52, 72), de tal maneira que um elemento de válvula (40; 42), quando de um movimento, após um determinado trajeto (S1), vem a encostar axialmente no outro elemento de válvula (42; 40) e movimenta conjuntamente o mesmo."FUEL INJECTOR DEVICE AND FUEL SYSTEM FOR INTERNAL COMBUSTION ENGINES AS WELL AS INTERNAL COMBUSTION ENGINE". A fuel injection device (10) for internal combustion engines comprises a housing (12) lengthened with an injection end (28). In the housing (12) extends in its longitudinal direction a recess (34). This is connectable with a fuel inlet (20). At least two axially spaced outlet openings (30, 32) are present at the injection end (28). At least two coaxially and axially movable valve members (40, 42) are arranged at least partially in the recess (34). They cooperate with valve seats in the region of the outlet ports (30, 32). In order to be able to construct the fuel injector device (10) as simple and small as possible, it is proposed that the valve elements (40, 42) have a drag connection (52, 72) such that a valve element (40; 42), when moving, after a certain path (S1), comes to axially abut the other valve element (42; 40) and move it together.
