Abstract
"VáLVULA GIRATóRIA PARA CAIXA DE DIREçãO MOTORIZADA", hidráulica, tendo uma manga (11), com entalhes (19a - b) fixada à guisa de mancal em um eixo da entrada (10) com ranhuras (18 a - c), com os entalhes de manga e ranhuras de eixo de entrada coatuantes 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 e secundárias dispostas em paralelo, cada ponte compreendendo dois membros, cada um dos quais incorpora orifícios de admissão e de retorno comunicando-se a respectivas passagens de admissão e de retorno da válvula. Os membros da ponte primária incorporam, meios provendo comunicação hidráulica com uma das passagens de cilindros, ao passo que os membros da ponte secundária não incorporam tais meios. O orifício de retorno (34a, 34b) em cada membro de ponte secundária é formado por um contorno de borda dosadora na borda de uma ranhura de retorno secundária (18c) e sobrepondo-se circunferencialmente a uma base de orifícios de manga adjacente, quando a válvula estiver em sua posição neutra, até uma medida tal que o orifício de retorno forneça uma restrição ao fluxo hidráulico em relação a todos os ângulos operacionais de válvula, aplicando assim uma contrapressão ao orifício de admissão a montante. A contrapessão é suficiente para suprimir significativamente a geração de ruído de cativão no orifício de entrada.
