Abstract
Patente de Invenção; <B>"SISTEMAS DE ATUAçãO HIDRáULICOS "<D>. Um sistema de atuação hidráulico (10) inclui um acumulador de pressão (12), uma bomba (16) que é conectada entre o acumulador de pressão (12) e um reservatório (14), a bomba (16) bombeamento o fluido do reservatório (14) para o acumulador de pressão (12), as válvulas de não recuo (18, 36) sendo localizadas entre o acumulador (12) e a bomba (16) e entre a bomba (6) e o reservatório (14) de modo a impedir o escoamento de fluido do acumulador (12) para a bomba (16) e da bomba (16) para o reservatório (14) respectivamente, e uma válvula de controle e solenóide (20) em uma primeira posição conectando o acumulador de pressão (12) e um cilindro escravo (34), e em uma segunda posição conectando o cilindro escravo (34) a um ponto entre a bomba (16) e a válvula de não recuo (36), de maneira que o fluido sob pressão possa ser bombeado do cilindro escravo (34) diretamente para o acumulador (12).
