Abstract

"INJETOR DE COMBUSTìVEL COM ATUAçãO ELETROMAGNéTICA DO êMBOLO". Um injetor de combustível (1) provido com um jato de injeção (3), uma válvula de injeção (7), a última tendo um êmbolo móvel (17) para regular o fluxo de combustível através do jato de injeção (3), e um atuador eletromagnético (6), que é capaz de deslocar o êmbolo (17) entre uma posição fechada e uma posição aberta da válvula de injeção (7), e tem um par de eletromagnetos (8), cada um tendo uma espira (11), uma armadura magnética fixa (12) e uma armadura móvel (9); na superfície externa de um corpo de suporte tubular (4) do injetor (1), são produzidas duas fendas anulares (15) em cada uma das quais tendo enrolada uma espira correspondente (11) de um eletromagneto (8).
