    • The invention relates to a process for regenerating a cryopump (1) with an inlet valve (33), pumping surfaces (6, 8, 11) at a temperature during the operation of the pump which results in the condensation and/or adsorption of gases, said surfaces being heated for the purpose of their regeneration, and a backing pump (45) connected to the inside of the pump (9) via a valve (44). In this process, with the inlet valve (33) closed and the connection between the inside of the pump (9) and the backing pump (45) closed, heating of the pump surfaces is started, so that both the temperature of the pump surfaces and the pressure inside the pump rise to values above the corresponding value of the triple point of the gas to be removed. The removal of the deposits released from the pump surfaces takes place in the liquid and/or gaseous stage via a line (46) with a regeneration valve (47) which is actuated dependently upon the pressure in the inside of the pump (9).
    • 本发明涉及一种用于在泵操作期间的温度下用入口阀(33)再生泵送表面(6,8,11)的低温泵(1)的过程,其导致气体的冷凝和/或吸附 所述表面被加热以便进行再生,以及通过阀(44)连接到泵(9)的内部的背衬泵(45)。 在这个过程中,当入口阀33关闭并且泵(9)和背衬泵(45)的内部之间的连接关闭时,开始泵表面的加热,使得泵表面的温度 并且泵内的压力升高到高于要去除的气体的三重点的对应值的值。 从泵表面释放的沉积物的去除通过经由具有再生阀(47)的管线(46)在液体和/或气态阶段中进行,再生阀(47)根据泵(9)内部的压力被致动。
