Abstract
Patente de Invenção:<B>"DISPOSITIVO DE DIREçãO HIDRáULICA E MéTODO PARA DIREçãO DE UM VEìCULO"<D>. Um dispositivo de direção hidráulica (1), em particular para veículos, é divulgado, tendo um alojamento no qual dois anéis corrediços estão dispostos a fim de se moverem um com relação ao outro e juntos formarem pelo menos um estrangulador ajustável (A1--A6, Ad), um dispositivo de restabelecimento para restabelecimento dos dois anéis corrediços para sua posição neutra sendo proporcionado, um dos dois anéis corrediços sendo acionável e o outro dois anéis corrediços estando em conexão funcional com um dispositivo de medição (7). Nesse dispositivo de direção é desejável aperfeiçoar a correlação entre o torque de direção e a amplificação do fluxo; em particular, é desejável linearizar a relação de forma melhor. Para essa finalidade, o dispositivo de medição (7) está disposto em um curso de fluxo fechado (8) em si e opera como uma bomba, ao passo que o curso de fluxo aberto (9) aciona o curso de fluxo fechado (8) a partir de uma estutura de conexão de entrada (P, T) para uma estrutura de conexão de saída (A, B).
