    • A self-rotating display device includes and outer light transmissive container (402) containing a light transmissive fluid (406) and an body (404) containing an electric motor (421) for rotating the body with respect to the outer container. The body also carries an amount of the fluid (430a) contacting the fluid in the outer container through a pressure equalizing gap (431) in the body which forms a fluid pathway between the inner cavity of the body and the inner chamber of the outer container. The fluid pathway forms self-regulating pressure relief structure which accommodates slight pressure variations in the fluid due to climactic conditions for example. A specialized reduced footprint fluid-immersible electric motor having separate field and compass magnets, which do not rotate relative to each other, helps eliminate magnetic cogging. The device can be manufactured according to a method which eliminates the necessity of a fill hole in the body.
    • 一种自转显示装置包括包含透光流体(406)的外透光容器(402)和包含用于相对于外容器旋转本体的电动机(421)的本体(404)。 本体还承载一定量的流体(430a),其通过本体中的压力平衡间隙(431)与外容器中的流体接触,该压力平衡间隙形成本体的内腔与外容器的内腔之间的流体通路 。 流体路径形成自调节的压力释放结构,其例如适应由于高潮状态引起的流体中的轻微压力变化。 具有独立的磁场和罗盘磁体的专用减小尺寸的流体浸没式电动机不会相对于彼此旋转,这有助于消除磁性齿槽效应。 该装置可以根据消除体内填充孔的需要的方法制造。
