    • The degree of freedom of a sound-absorbing device in terms of size is increased, maintaining easy mounting operation of the sound-absorbing device, even if the sound-absorbing device has a greater length.The sound-absorbing device 1, which alleviates and absorbs a sound generated by fuel movement in a fuel tank in such a state that the sound-absorbing device is put into the tank through an opening E formed in the tank and is mounted to the tank, has a three-dimensional structure, which has a narrower width X than a width of the opening and a greater length Y than the width of the opening E; and the sound-absorbing device comprising plural sound-absorbing parts 2A and 2B coupled together through a coupling portion 3 in an intermediate position in a longitudinal direction extending along the length Y.

    • An anti-slosh device for attenuating oscillations of liquids in tanks caused by movement of vehicles in which the tank is located comprises an elongated flat, rectangularly, shaped, uniform thickness strip of a liquid impervious material such as polyethylene or polycarbonate which is formed into a string of arcuately curved loops. One embodiment of the device has located at opposite ends thereof spirally-shaped, quasi-helical end loops which form a figure-8 shape, and a center loop disposed obliquely between the end loops. A two-loop version of the device has two end loops but no center loop. The anti-slosh device is used to reduce the duration of undesirable oscillations induced in a liquid in a tank by placing a plurality of the devices in the interior of a tank, as by inserting a plurality of the devices through a fill tube or other access port of the tank. Non-parallel surfaces of the device function as baffles, converting large scale linear motions of liquid in a tank to small scale, energy-dissipating vortices, thus reducing the duration and amplitude of oscillations of liquid in the tank.
    • 用于衰减由罐位于其中的车辆的运动引起的罐中液体振动的防晃动装置包括长条形的扁平的,矩形的,形状均匀的不透液体材料的厚度条,例如聚乙烯或聚碳酸酯,其形成为 一串弧形曲线。 该装置的一个实施例位于形成图形8的螺旋状准准螺旋端环的相对端,以及倾斜地设置在端环之间的中心环。 设备的双循环版本有两个端环,但没有中心环。 防晃动装置用于通过将多个装置放置在罐的内部来减少在罐中的液体中引起的不期望的振荡的持续时间,如通过将多个装置插入通过填充管或其它通路 坦克港 该装置的非平行表面用作挡板,将罐中液体的大规模线性运动转换成小尺度,能量消散的涡流,从而减少罐中液体振荡的持续时间和振幅。
