Abstract
Patente de Invenção "MéTODO E DISPOSITIVO PARA PROPORCIONAR UMA TAXA CONTROLADA DE INJEçãO E PRESSãO DE INJEçãO EM UM CONJUNTO INJETOR DE COMBUSTìVEL", caracterizado por compreender um método de controlar a taxa e pressão de injeção de um conjunto de injetor eletromagnético de combustível tendo uma válvula de controle de pressão balanceada incluindo um solenóide a um elemento de válvula sujeito às pressões desenvolvidas pelo injetor e atuada pelo solenóide para fechar o elemento de válvula contra a força de empuxo de uma mola. A válvula de controle é suportada em um orifício de válvula no corpo do injetor. O orifício da válvula inclui uma porção em relevo. O método inclui a etapa de proporcionar um primeiro nível de corrente ao solenóide para movimentar o elemento de válvula de uma posição aberta a uma fechada permitindo o aumento de pressão no injetor em ocasiões previamente selecionados durante a injeção para desequilibrar as forças que atuam sobre o elemento de válvula, movendo assim levemente o elemento de válvula em seu assento para regular a pressão e taxa de injeção do injetor de combustível e cortando a corrente ao solenóide movimentando assim o elemento de válvula para sua posição aberta.
