Abstract

"VáLVULA GIRATóRIA PARA CAIXA DE DIREçãO MOTORIZADA", hidráulica, tendo uma manga com entalhes fixada à guisa de mancal em um eixo de entrada com ranhuras, com os entalhes de manga e ranhuras de eixo de entrada co-atuantes definindo orifícios estendendo-se axialmente. Os orifícios comunicam-se à guisa de passagens como uma rede, de tal modo que os mesmos formem pontes de Wheatstone hidráulicas primárias (29) e secundárias (30) dispostas em paralelo, cada ponte compreendendo dois membros, cada um dos guias comunica orifícios de admissão e de retorno a respectivas passagens de admissão e de retorno da válvula. Os membros da ponte primária comunicam-se hidraulicamente com uma das respectivas passagens de cilindros (4,5), em um ponto de interconexão dos respectivos orifícios de admissão e de retorno desse membro. Os membros de ponte secundária não se comunicam hidraulicamente com as passagens de cilindros. O fluxo hidráulico das pontes primárias e secundárias é comunicado hidraulicamente à passagem de retorno através de respectivos trajetos de retorno primários e secundários. O trajeto de retorno secundário tem uma restrição anular (71) tendo uma seção transversal ao fluxo, a qual tem uma elevada razão de aspecto.
