Abstract

Patente de Invenção: <B>"INVóLUCRO FENDIDO PARA INJETOR DE COMBUSTìVEL"<D>. Um injetor de combustível atuado com solenóide inclui um invólucro de bobina circundando uma bobina de solenóide e formando uma pare de um circuito magnético que abre uma válvula de injeção quando a bobina é energizada. Para acelerar o fechamento da válvula na desenergização da bobina de solenóide, o invólucro de bobina tem fendas estreitas que se estendem na direção do campo magnético para reduzir o desenvolvimento e o fluxo de correntes parasitas no invólucro de bobinas que retardam o colapso do campo magnético e fechamento da válvula. As fendas estendem-se perpendiculares à direção do fluxo de corrente parasita e assim aumenta a resistência ao fluxo de corrente, através do invólucro de bobina nesta direção. Elas também reduzem a quantidade de material magnético no invólucro de bobina e assim reduzem a quantidade de correntes parasitas criadas durante o colapso de campo.
