Abstract

"INJETOR DE COMBUSTìVEL COM UM DISPOSITIVO AUTI-RICOCHETE". Onde, em um injetor de combustível (1), tendo uma válvula de injeção (7) com um pino móvel (15) e um atuador (5) para mover o pino (15) entre uma posição fechada e uma posição aberta, o atuador (5) tem uma armadura (10) móvel e um dispositivo (20) anti-ricochete interposto entre a armadura (10) móvel e o pino (15) para conectar mecanicamente a armadura (10) móvel e o pino (15), o dispositivo (20) anti-ricochete tendo um prato deformável elasticamente (32, 45, 48) o qual tem um formato anular, está conectado no centro com o pino (15) e está conectado na lateral com a armadura (10) para transmitir ao menos o movimento de fechamento da válvula de injeção (7) desde a armadura (10) até ao pino (15).
