Abstract

"SISTEMA DE DIREçãO DE ACIONAMENTO HIDROSTáTICO", compreendendo um motor de fluído (19) que recebe fluido pressurizado de um controlador (17) em resposta à rotação de um volante de direção de veículo (W). Quando o motor (19) ou as rodas direcionais alcançam os batentes, uma lógica de controle (31) recebe sinais (37, 77) representando a posição de roda direcional e a posição de volante de direção, respectivamente, e gera sinais de comando apropriados (33, 27) para uma válvula de redução/alívio de pressão (15) e para uma válvula eletromagnética proporcional (23), respectivamente, fechando um pouco a válvula
