Abstract

Patente de Invenção: "ATUADOR DE VáLVULA DE MOTORHIDRAULICAMENTE ASSISTIDO". Atuador de válvula de motorhidraulicamente assistido para ajudar na atuação de uma válvulade motor, que inclui um servopistão que é operavelmente acopladoà válvula de motor. Uma válvula piloto trasladável está emcomunicação de fluido com o servopistão e o pistão principal e éoperavelmente acoplada a um sistema de posicionamento deválvula piloto e controlada pelo mesmo. O sistema deposicionamento de válvula piloto controla um curso de trasladaçãoda válvula piloto para medir o fluido hidráulico sob pressão para e apartir do servopistão. Um ampliador de curso amplia um curso dosistema de posicionamento de válvula piloto.
