Abstract

<B>"SISTEMA DE DIREçãO SERVO-ASSISTIDO E RESPECTIVO ARRANJO DE VáLVULAS"<D>. A invenção está relacionada a um sistema de direção com assistência hidráulica para um veículo motorizado. Devido ao fato de que está associada ao sistema hidráulico uma válvula eletromecânica 12 que, na posição aberta, conecta hidraulicamente de maneira direta ou indireta as câmaras de trabalho 3, 4, é possível dispensar as válvulas limitadoras de pressão, válvulas de sucção secundárias e válvulas de interrupção limite convencionais.
