Abstract

Patente de Invenção: "VáLVULA INJETORA DE COMBUSTìVEL". Com relação a uma válvula injetora de combustível para motores de combustão, com um alojamento de válvula, com um componente de válvula axialmente móvel, previsto para abrir e fechar uma abertura de injeção da válvula injetora, e com uma peça do componente de válvula, atuante em direção de fechamento, a qual, com sua extremidade afastada da abertura de injeção, desloca-se em uma perfuração de uma primeira peça de válvula, inserida no alojamento da válvula, e com esta extremidade circunda, na primeira peça de válvula, um compartimento pressurizado de comando, o qual, por um canal adutor, provido, ao menos, de um estrangulador adutor, com uma conexão de alta pressão de combustível, e através de canal de escoamento, que pode ser fechado por um componente de válvula de comando, e possuindo um estrangulador de escoamento, pode ser unido com uma conexão de baixa pressão de combustível, sendo que através da pressão do combustível no compartimento pressurizado de comando pode ser controlado o processo da injeção, é proposto que ao menos o segmento do canal adutor, provido do estrangulador adutor, esteja disposto em uma segunda peça de válvula, inserida no alojamento da válvula, sendo que a referida segunda peça de válvula está de tal modo ligada com uma abertura, configurada na primeira peça de válvula, que o segmento do canal adutor da segunda peça de válvula, provida com o estrangulador adutor, desemboca no compartimento pressurizado de comando da primeira peça de válvula.
