Abstract

"acionador eletromagnético". o acionador eletromagnético compreende uma bobina (1), um órgão de acionamento magnético (3) montado na bobina, pelo menos um anel (6) feito de material magnético disposto em torno da bobina, e pelo menos um imã permanente (5) contíguo a uma extremidade do anel e disposto em frente a uma parte de superfície externa da bobina (1), o ímã permanente tendo um campo de imantação que se estende de acordo com uma direção axial da bobina (1), o órgão de acionamento magnético sendo montado deslizante dentro de um órgão não magnético de guia (2) que se estende na bobina e o anel tendo uma extremidade oposta ao imã que é separada do órgão não magnético de guia por um intervalo não magnético.
