Abstract
uma servoválvula compreendendo um motor, um mecanismo de polarização de motor, um membro de válvula de primeiro estágio adaptado para ser movido a partir de uma primeira posição para uma primeira posição não nula, um membro de segundo estágio adaptado para ser movido a partir de uma primeira posição para uma segunda posição com movimento do primeiro membro de válvula, uma ligação de transferência atuando entre os primeiro e segundo membros de válvula, um membro de acionamento excêntrico atuando entre o motor e a ligação de transferência, a ligação de transferência e o membro de acionamento configurados de modo que o movimento seletivo do motor faz com que a ligação de transferência mova o primeiro membro de válvula, o movimento do primeiro membro de válvula faz com que o segundo membro de válvula se mova, e o movimento do segundo membro de válvula faz com que a ligação de transferência mova o primeiro membro de válvula a partir da primeira posição não nula de volta para a posição nula.
