Abstract

"BOCAL INJETOR DE COMBUSTìVEL PARA MOTORES DE COMBUSTãO COM AUTO-IGNIçãO". Um bocal injetor de combustível para motores de combustão interna com auto-ignição com um corpo de bocal, em que na extremidade do lado da injeção de uma perfuração está formada uma área de sede de válvula cónica, da qual partem furos de injeção, e com uma agulha de válvula abrindo contra uma força de fecho contra a direção de corrente do combustível, a qual está guiada deslocável na região de entrada da perfuração oposta à extremidade do lado de injeção e apresenta em seu lado voltado para a área de sede de válvula um cone de fecho, que coopera com a área de sede de válvula, é caracterizado pelo fato de que a seção transversal do furo de injeção é novamente alargada para o compartimento de combustão do motor de combustão interna depois de estreitamento inicial.
