Abstract

"SISTEMA DE ACIONAMENTO HIDRáULICO POR COMANDO ELéTRICO". De acordo com a invenção, um circuito hidráulico (17) e uma válvula de comando (18) são dimensionados para poder efetuar a grande maioria dos acionamentos do leme (3), os quais necessitam uma potência inferior às performances máximas do sistema. Além disso, uma bomba hidráulica bidirecional (23), acionada por um motor elétrico (34), pode fornecer uma potência complementar a qual, somada à potência do dito circuito (17), permite assegurar as ditas performances máximas.
