Abstract

Patente de Invenção: <B>"INJETOR DE COMBUSTìVEL COM VáLVULA DE ESFERA"<D>. Um injetor de combustível acionado por solenóide inclui um corpo de válvula, um assento de válvula em uma extremidade do corpo de válvula e possuindo uma superfície de assentamento voltada para o interior do corpo de válvula e incluindo uma abertura de saída de combustível, um tubo de combustível para conduzir o combustível sob pressão para o interior do corpo de válvula contra a superfície de assentamento, uma válvula de esfera esférica móvel entre uma posição assentada contra a superfície de assentamento para fechar a abertura de saída contra um fluxo de combustível, e uma posição aberta afastada da superfície de assentamento para permitir um fluxo de combustível através da abertura de entrada, uma mola no corpo de válvula e predispondo a válvula de esfera na direção da posição assentada, uma armadura móvel no sentido axial no corpo de válvula e incluindo um membro de captura da válvula de esfera em uma extremidade próxima da superfície de assentamento, podendo o membro de captura da válvula de esfera engajar a superfície externa da esfera adjacente à superfície de assentamento, e uma bobina de solenóide que opera para afastar a armadura da superfície de assentamento, assim movimentando a válvula de esfera para a posição aberta e permitindo que o combustível passe através da abertura de saída de combustível, a desativação da bobina do solenóide permite que o meio de predisposição faça a válvula de esfera retornar para a posição assentada contra a superfície de assentamento e se alinhe na posição assentada, fechando, desta forma, a abertura de saída contra a passagem de combustível. Um método de montagem do injetor de combustível acionado por solenóide inclui as etapas de montar um subconjunto de grupo de válvula, montar um subconjunto de grupo de bobina, montar em conjunto o subconjunto de grupo de válvula com o subconjunto de grupo de bobina, e fixar juntos por pressão as características cooperantes de fixação por pressão nos subconjuntos de grupo de válvula e grupo de bobina.
