Abstract

"BOMBA ,INJETOR DE COMBUSTìVEL, VáLVULA DECONTROLE, E, MOTOR". Bombas (6) e injetores (4) utilizam umaválvula de controle (46) tendo um corpo da válvula (48), com umahaste da válvula (88) tendo um degrau (94) adjacente à superfíciede assentamento (92). O degrau se estende por uma distâncialimitada para fora da superfície de assentamento, de forma aproporcionar alívio de pressão limitado, quando o corpo da válvulaficar em uma posição intermediária que esteja entre as posiçõesaberta e fechada. A seção transversal e o comprimento axial dodegrau podem ser configurados com base no comportamentohidráulico desejado. Em uma modalidade preferida, o degrau daválvula de controle é configurado para ajuste da taxa de injeção.
