    • A mechanical-hydraulic damper for a load which is subject to shocks and vibrations, comprising a co-operating pair of elements, the first of the pair of elements being mounted in a body for relative axial movement in relation to the body and the second of the pair of elements being rotatably mounted in the body and so coupled to the first element that relative axial movement of the first element causes rotation of the second element which is coupled to a hydraulic system which resists sudden or rapid rotation of the second element. The pair of co-operating elements may comprise a screw-nut assembly. The hydraulic system may comprise a reversible pump driven by the rotatable element and pumping hydraulic fluid round a closed circuit including a throttling orifice. Alternatively the hydraulic system may comprise a rotary laminar hydraulic damper filled with high viscosity oil.
    • 一种用于承受冲击和振动的负载的机械液压阻尼器,包括一对配合的元件,所述一对元件中的第一个元件安装在主体中,用于相对于主体相对轴向移动,第二个元件 所述一对元件可旋转地安装在所述主体中并且联接到所述第一元件,所述第一元件的相对轴向运动引起所述第二元件的旋转,所述第二元件联接到抵抗所述第二元件的突然或快速旋转的液压系统。 一对协作元件可以包括螺母 - 螺母组件。 液压系统可以包括由可旋转元件驱动的可逆泵,并且在包括节流孔的闭合回路的周围泵送液压流体。 或者,液压系统可以包括填充有高粘度油的旋转层流液压阻尼器。
