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.
