    • A vibratory road roller has a drum adapted to be vibrated as it rolls along the ground, to this end the drum containing a vibrator device of the type which produces a vibratory effect as a result of rotation of an out-of-balance mass. The vibrator device comprises a casing, fixed to an end plate of the drum, and a rotor which has a fluid-containing cavity with the contained body of fluid contacting a swept internal annular surface of the casing. A piston movable radially in the rotor and/or the body of fluid provides the out-of-balance mass, and the vibratory force is transmitted to the casing and hence to the drum by the fluid pressure acting on the swept annular surface of the casing. The rotor structure itself is mechanically balanced so that substantially no vibratory force is transmitted through the rotor shaft and bearings.
    • 振动压路机具有适于沿着地面滚动的振动的滚筒,为此,该滚筒包含由于失去平衡质量的旋转而产生振动效应的振动器装置。 振动器装置包括固定到滚筒的端板的壳体和具有流体容纳腔的转子,该流体容纳腔与容纳的流体接触壳体的扫过的内部环形表面。 在转子和/或流体中径向移动的活塞提供了不平衡的质量,并且振动力通过作用在壳体的扫过的环形表面上的流体压力而被传递到壳体 。 转子结构本身是机械平衡的,使得基本上没有振动力通过转子轴和轴承传递。

    • Vibrator devices, of the type which produce a vibratory effect as a result of rotation of an out-of-balance mass, comprise a casing and a rotor which has a fluid-containing cavity with the contained body of fluid contacting a swept annular surface of the casing. A piston movable radially in the rotor and/or the body of fluid provides the out-of-balance mass and the vibratory force is transmitted to the casing directly by the fluid pressure on the swept annular surface thereof. The rotor structure is mechanically balanced so that substantially no vibratory force is transmitted through the rotor shaft and bearings.

    • A vibrating drum for soil tamping machines, including a cylindrical tubular skirt adapted to be arranged in abutment against soil to be tamped to which is associated a first hydraulic motor which rotates the tubular skirt around a central shaft to move the tubular skirt forward, and a vibration mechanism to make the tubular skirt vibrate. The vibration mechanism includes a second hydraulic motor coupled to an end of the central shaft and a receptacle fastened to the central shaft which delimits a chamber for containing a liquid in which is partly immersed a draught pipe connected to a hydraulic circuit, which includes a pumping mechanism adapted to change an amount of liquid contained in the chamber so as to change the vibration amplitude of the drum.
