Abstract

a presente invenção refere-se a uma válvula de controle de fluxo para um ventilador que controla o fluxo de gás através de uma linha de paciente em resposta a uma pressão alvo dentro da linha. a válvula controla o fluxo de gás (i) provendo tanto um sinal de alta frequência quanto um sinal de baixa frequência através de uma bobina posicionada em um campo magnético fixo, (ii) determinando uma posição da bobina detectando o sinal de alta frequência, e (iii) controlando uma posição da bobina ajustando o sinal de baixa frequência com base na posição e/ou velocidade determinadas da bobina.
