    • An X-ray tube equipped with a rotating anode cartridge comprising a reinforced sealing system. This sealing system is achieved in three complementary manners. Firstly, when the anode rotates, in order to confine the liquid alloy within the cartridge, the invention provides to equip the two surfaces of a leak-tight joint with grooves thereby obtaining a double sided joint with an improved efficiency. Secondly, the double sided joint makes it possible to obtain, for the vacuum tightness, when the anode shaft is not rotating, two spaces limited by the surface tension of the alloy of liquid metal. The more symmetrical these two spaces, the more the sealing is reinforced. Thirdly, the invention provides to separate the ring from the axis of rotation. This enables a joint centering the two spaces in an automatic and natural manner to be obtained.
    • 一种装有旋转阳极筒的X射线管,包括一个加强的密封系统。 该密封系统以三种互补的方式实现。 首先,当阳极旋转时,为了将液体合金限制在盒内,本发明提供了使密封接头的两个表面装配槽,从而获得了提高效率的双面接头。 其次,双面接头可以获得真空密封性,当阳极轴不旋转时,由液态金属合金的表面张力限制两个空间。 这两个空间越对称,密封越强化。 第三,本发明提供了将环与旋转轴分离。 这使得能够以自动和自然的方式对两个空间进行联合定心。
