There is described an aircraft (1) comprising a transmission unit (9) having a first module (11, 13, 15) and a lubrication system (25, 25 '); the first module (11, 13, 15) comprises a housing (20) and a movable member (17, 18, 19); the lubrication system (25, 25 ') comprises a header (26), a nozzle (27, 28) supplied with a lubrication fluid and designed to supply the lubrication fluid inside the housing (20) of the first module (11, 13, 15), a collection tank (30, 100') for the lubrication fluid injected by the nozzle (27, 28), and a recirculation device (35) designed to recirculate the lubrication fluid from the collection tank (30, 100 ') to the supply header (26); the first module (11, 13, 15) comprises a valve (60, 60 ') usable in a first configuration when the pressure of the lubricating fluid in the header (26) is greater than a threshold value and in a second configuration when the pressure of the lubricating fluid in the header (26) is less than the threshold value, in the first configuration, the valve enables the lubricating fluid to flow from the module (11) to the recirculation means (35); in a second configuration, the valve fluidly isolates the module (11) from the recirculation device (35).
描述了一种航空器(1),其包括具有第一模块(11、13、15)和润滑系统(25、25’)的传输单元(9);第一模块(11、13、15)包括外壳(20)和可动构件(17、18、19);润滑系统(25、25’)包括集管(26)、被供给润滑流体并被设计为将润滑流体供给到第一模块(11、13、15)的外壳(20)内部的喷嘴(27、28)、用于由喷嘴(27、28)喷射的润滑流体的收集罐(30、100’)以及被设计为使润滑流体从收集罐(30、100’)再循环到供给集管(26)的再循环装置(35);第一模块(11、13、15)包括阀(60、60’),该阀能在集管(26)内的润滑流体的压力大于阈值时以第一构造使用和在集管(26)内的润滑流体的压力小于阈值时以第二构造使用,在第一构造中,该阀使所述润滑流体能够从所述模块(11)流出到再循环装置(35);而在第二构造中,该阀将模块(11)与再循环装置(35)流体地隔离。
