Abstract
"INJETOR". Trata-se de um injetor compreendendo um corpo (10), um estilete (12) de válvula deslizável no interior do corpo e sendo feito tender em orientação para contato com um dispositivo de assento por intermédio de uma mola (20), uma linha (62) de alimentação de combustível para fornecimento de combustível para superfícies de impulsão providas sobre o estilete de válvula para aplicação de uma força sobre o estilete de válvula atuando em oposição à ação da mola, uma válvula (74) de dreno operável para controlar a comunicação entre a linha de alimentação e um dreno de baixa pressão, uma válvula (30) de controle de estilete controlando a pressão de combustível no interior de uma câmara de controle (38) definida, em parte, por uma superfície do estilete de válvula ou um componente transportado pelo mesmo sendo orientada de tal forma que quando é aplicada uma alta pressão de combustível para a câmara de controle, é aplicada uma força ao estilete de válvula em uma direção de cooperação com a mola, em que a válvula de dreno e a válvula de controle de estilete são controladas por um dispositivo de atuador eletromagnético incluindo um único induzido (88), a válvula de controle de estilete e a superfície do estilete de válvula ou de um componente transportado pelo mesmo definindo uma parte da câmara de controle possuindo dimensões mediante as quais a válvula de controle de estilete encontra-se sob uma pressão substancialmente balanceada em todos os momentos.
