Title
(PT) conjunto de motor, sistema de controle de fluidos e método de operação de um inversor de empuxo do motor
Abstract
(PT) um conjunto de motor inclui uma nacela configurada para envolver pelo menos parcialmente um motor e um inversor de empuxo acoplado à nacela. o inversor de empuxo inclui: um elemento de inversão de empuxo móvel em relação à nacela entre uma posição retraída e uma posição estendida; um atuador hidráulico acoplado operacionalmente para mover o elemento de inversão de empuxo; e um sistema de controle de fluidos configurado para operar o atuador hidráulico. o sistema de controle de fluidos inclui: uma unidade de controle direcional incluindo uma válvula de controle direcional operável para direcionar seletivamente o fluido entre uma fonte de fluido pressurizado, o atuador e um reservatório de retorno de fluido; uma ou mais linhas de fluido de passagem, proporcionando comunicação fluida entre o atuador e o reservatório de retorno de fluido, independentemente da válvula de controle direcional; e um limitador de fluxo localizado entre a fonte de fluido pressurizado e a válvula de controle direcional, o limitador de fluxo configurado para inibir uma pressão exercida pelo atuador de ultrapassar um limite predeterminado.
