Abstract

"VáLVULA INJETORA DE COMBUSTìVEL PARA MOTORES DE COMBUSTãO". Conjunto de alimentação de combustível com um alojamento (1), no qual está disposto longitudinalmente deslocável um componente construído em formato de pistão (5) no interior de uma perfuração (3), deslocando-se com um segmento condutor (105) de forma vedada dentro da perfuração (3). No caso, o segmento condutor (105) estabelece limite em uma extremidade com um primeiro compartimento (19) cheio de combustível e na sua outra extremidade estabelece limite com um segundo compartimento cheio de combustível (15). No segmento condutor (105) do componente construído em formato de pistão (5) está configurada ao menos uma reentrância (30) que se estende ao menos aproximadamente em direção circunferencial, estendendo-se ao menos sobre uma parte da circunferência do componente construído em formato de pistão (5) e que, visto em direção longitudinal do componente construído em formato de pistão (5), apresenta uma seção transversal assimétrica.
