Abstract

SERVOVáLVULA CONTINUAMENTE VARIáVEL ATUADA POR SOLENóIDE PARA AJUSTE DE AMORTECIMENTO EM ABSORVEDORES DE CHOQUE E LONGARINAS. Um obsorvedor de choque (1) inclui um tubo de pressão com um pistão disposto de forma deslizante ali. Uma válvula separada inclui um circuito de fluido para escoamento de fluido para escoamento de fluido em compressão. Cada circuito de fluido inclui um orifício variável o qual permite uma seleção entre um recuo firme com uma compressão suave, um recuo suave com uma compressão suave e um recuo suave com uma compressão firme Cada orifício variável está em comunicação com uma válvula de extração, de maneira tal que eles provejam um recurso de extração variável para as válvulas de extração, como mostrado na figura 5.
