Abstract

Patente de Invenção: "DISPOSITIVO PARA A INJEçãO DIRETADE COMBUSTìVEL EM UMA MáQUINA DE COMBUSTãO DEêMBOLO". A invenção refere-se a um dispositivo (10) para ainjeção direta de combustível em uma máquina de combustão deêmbolo, que apresenta um comando de válvula (12) hidráulico,com válvulas de troca de gás (22) que podem ser acionadashidraulicamente. A invenção propõe ligar a injeção direta decombustível ao comando de válvula (12) hidráulico, através de umtransmissor de pressão (50) para dois meios de pressão distintos,cujo transmissor de pressão é admitido com óleo hidráulico de umreservatório de alta pressão de óleo hidráulico (20) do comando deválvula (12) hidráulico, e que admite um reservatório de altapressão de combustível (78) com alta pressão, sendo que noreservatório de alta pressão de combustível (78) estão conectadasválvulas de injeção de combustível (80) para a injeção direta decombustível na máquina de combustão de êmbolo.
