    • A packing seal for closing the space between a rotating shaft and a stationary machine part is described. A ring is located in an annular slot formed in one of the shaft or machine parts. The ring is tensioned radially on the rotating or on the non-rotating part and axially spaced from the frontal faces of the slot so that a fluid media can be located therebetween. At least one face of the ring has a plurality of arcuate grooves by which the pressure of the fluid medium between the ring and the opposing frontal face of the slot is generated on rotation of said shaft.
    • 描述用于封闭旋转轴和固定机器部件之间的空间的填料密封件。 环位于形成在轴或机器部件之一中的环形槽中。 环在旋转的或非旋转的部分上径向张紧,并且与槽的前表面轴向间隔开,使得流体介质可以位于它们之间。 环的至少一个面具有多个弧形槽,通过该多个弧形槽,在所述轴和所述槽的相对的前表面之间的流体介质的压力在所述轴的旋转时产生。
