Abstract
patente de invenção: "válvula de injeção de combustível". a presente invenção refere-se a uma válvula de injeção de combust´vel que se distingue, particularmente, pelo fato de que é gerada uma afluência uniforme e temporalmente estável das aberturas de injeção (32) e, portanto, é obtida uma redução de dispersão nas características de jato e passagem. a válvula de injeção de combustível (1) compreende pelo menos um elemento de ativação excitável, bem como um elemento de válvula, que pode ser movido ao longo de um eixo longitudinal de válvula, que interage de modo hermético com um assento de válvula (28). a montante de assento de válvula (28) estão previstas várias regiões de passagem (26) sobre a circunferência, entre as quais se situam, em cada caso, regiões de guia (30) para o elemento de válvula. as aberturas de injeção (32) a jusante do assento de válvula (28), cujo número diverge do número das regiões de passagem (26), distribuem o combustível de modo finamente atomizado. pelo menos duas regiões de passagem (26) diferenciam-se em tamanho, tal como largura circunferencial e/ou profundidade radial e/ou contorno. a válvula de injeção de combustível é particularmente apropriada para a injeção direta de combustível em uma câmera de combustão de um motor de combustão interna de ignição independente, compressor de mistura.
