Abstract
Patente de Invenção "CONJUNTO INJETOR DE COMBUSTìVEL, COM VáLVULAS DE RETENçãO APRIMORADA, ACIONADA POR SOLENóIDE", caracterizado pelo fato de compreender um conjunto injetor de combustível para motor de combustão interna incluindo incluindo um corpo do injetor em comunicação líquida com uma fonte de combustível e conjunto de bico através do qual o combustível é disperso do conjunto de injetor de combustível durante um caso de injeção. Um sistema de liberação de combustível de alta pressão fornece alta pressão para o conjunto de bicos. O corpo do injetor define uma galeria de derramamento de combustível de baixa pressão no qual um combustível não usado é coletado do sistema de liberação de combustível de alta pressão. O sistema de liberação de combustível de alta pressão inclui um furo cilíndrico, um êmbolo apoiado por movimento alternativo dentro do furo cilíndrico, uma câmara de bomba definida pelo êmbolo e o furo cilíndrico, e uma passagem de combustível de alta pressão que se estende através do corpo do injetor da câmara da bomba até o conjunto de bicos para dispersar combustível a alta pressão do conjunto de injetor. Uma válvula de retenção acionada por solenóide é localizada entre a câmara de bomba e conjunto de bicos e entre a galeria de derramamento de combustível de baixa pressão e passagem de combustível de alta pressão. A válvula de retenção opera para controlar a pressão no sistema de liberação de combustível, reduzindo alternadamente a pressão no sistema de combustível ou aumentando a pressão no sistema de liberação de combustível abrindo e fechando o mesmo.
