Abstract
Patente de Invenção: "CAPTADOR DE POSIçãO AXIAL PARA UMA HASTE MóVEL AXIALMENTE E ACIONADOR ELETROMAGNéTICO DE VáLVULA QUE EQUIPA ESSE CAPTADOR". Captador de posição axial para uma haste (1) deslocável axialmente entre duas posições extremas, compreendendo: uma luva magnética (4) com imantação radial, fixada coaxialmente sobre a haste (1) que é, pelo menos superficialmente, magnética; um detector fixo de fluxo magnético (5) compreendendo: dois anéis (6A, 6B) em material ferromagnético, envolvendo coaxialmente, à distância radial (e), a luva imantada (4) e afastadas axialmente uma da outra, esses dois anéis que comportam, em suas extremidades respectivas frontais, dois ressaltos radiais (7A, 7B) respectivos sobre as quais são aplicadas duas sondas de Hall (8A, 8B), associadas funcionalmente a meios de cálculo (9) fornecendo um sinal representativo da relação da diferença à soma dos fluxos magnéticos que passam pelas sondas, relação essa que é ela própria representativa da posição axial da haste (1); e meios (18) de retorno dos fluxos magnéticos.
