摘要： A tandem hydraulic valve comprising first and second axially aligned valve spools, a valve guide slidably receiving said valve spools to control, in use, the connection between respective ports of the valve guide, said first and second spools being formed as separate components and being axially interconnected, to move in unison, by an axial connection component, and, the interface of said first and second spools being connected to a predefined, external, hydraulic fluid leakage path.

摘要： A failsafe arrangement comprising a first mounting member and a second mounting member which is angularly moveable relative to the first mounting member. The first and second mounting members define first and second surfaces respectively which define therebetween a channel, the first and second surfaces being shaped such that the channel is of non-uniform width. At least one wedge member is disposed within the channel, the or each wedge member being carried by a drive member and being arranged such that, in use, when the drive member and the second mounting member move at substantially the same angular speed, the wedge member does not impair movement of the second mounting member relative to the first mounting member, relative angular movement of the drive member and the second mounting member causing the wedge member to cooperate with the first and second surfaces to apply a braking force so as to impede relative angular movement of the first and second mounting members. In use, the first mounting member may be secured to an aircraft wing and the second mounting member may be secured to an aircraft wing flap.
摘要翻译：一种故障安全装置，包括第一安装构件和相对于第一安装构件成角度地移动的第二安装构件。第一和第二安装构件分别限定在其间限定通道的第一和第二表面，第一和第二表面被成形为使得通道具有不均匀的宽度。至少一个楔形构件设置在通道内，该楔形构件或每个楔形构件由驱动构件承载并且被布置成使得在使用中，当驱动构件和第二安装构件以基本上相同的角速度移动时，楔形构件构件不会损害第二安装构件相对于第一安装构件的运动，驱动构件和第二安装构件的相对角度运动使楔形构件与第一和第二表面协作以施加制动力，第一和第二安装构件的相对角运动。在使用中，第一安装构件可以固定到飞行器机翼，并且第二安装构件可以固定到飞行器机翼翼片。
