Abstract

"CONJUNTO DE BOMBA INJETORA PARA COMBUSTìVEL LìQUIDO PARA UM MOTOR DE COMBUSTãO INTERNA, E, CONJUNTO DE VáLVULA AMORTECEDORA". Uma bomba injetora de combustível para um motor de combustão interna que inclui um êmbolo de distribuição de combustivel acionado por eixo de cames 38, uma válvula solenóide 82 para controlar transferência de combustível líquido a partir de uma cavidade de êmbolo de combustivel 40 até um bocal injetor de combustivel 16, e uma válvula amortecedora 64 localizada entre o bocal injetor de combustivel 16 e o embolo 38, pelo que, escoamento de combustivel não restrito é distribuído para o bocal injetor 16 e escoamento inverso a partir do bocal 16 a até a câmara do êmbolo é restrito de modo que cavitação na passagem de distribuição de combustível 52 que se estende para o bocal 16, será evitada e picos de pressão indesejáveis na bomba de combustivel são evitados.
