Abstract

ARQUITETURA PARA UM SISTEMA HIDRáULICO. A invenção diz respeito a uma arquitetura pra um sistema hidráulico para operar trem de pouso de uma aeronave que inclui pelo menos uma fonte de pressão hidráulica e pelo menos um retomo hidráulico, o sistema tendo um circuito hidráulico compreendendo uma primeira linha hidráulica ("DOWN") que, quando pressurizada, faz com que o trem de pouso seja abaixado, e uma segunda linha hidráulica ("UP" 5) que, quando pressurizada, faz com que o trem de pouso seja recolhidos, as ditas linhas sendo pressurizadas seletivamente por meio de um elemento de distribuição hidráulico (10, 12) compreendendo pelo menos uma válvula de isolamento (10) e um seletor (12) para por uma das Linhas em comunicação com pressão e a outra linha em comunicação com o retorno. De acordo com a invenção, a arquitetura inclui meio de conexão de desvio passivo (54, 55) para desviar do seletor, o dito meio sendo disposto entre a segunda linha ("UP" 5) e uma linha de admissão (20) que estende-se entre a válvula de isolamento e o seletor, e meio de conexão de retomo forçado (53) para forçar a válvula de isolamento (10) a isolar o circuito de pressão da aeronave e conectar a linha de admissão no retorno.
