摘要： The invention relates to a pump (1) having a shaft (4) and an impeller (5) which is arranged on the shaft, and having a labyrinth seal (9A,9B) which is arranged between stationary and moving parts of the pump, with a plurality of blades (6) being arranged on the rotor (2) and with a labyrinth seal extending at least between the shaft and a blade rear (12) of the blades. The gap in the labyrinth seal is designed such that liquid water can be actively carried away, with the labyrinth seal for this purpose being designed at least in places with a channel (14, 17, 18) in the form of a spiral and/or a staircase. The invention also relates to a fuel cell system having a pump such as this.
摘要翻译：本发明涉及一种具有轴（4）和布置在轴上的叶轮（5）的泵（1），并且具有布置在泵的静止部分和运动部分之间的迷宫式密封件（9A，9B）其中多个叶片（6）布置在所述转子（2）上并且具有至少在所述轴和所述叶片的叶片后部（12）之间延伸的迷宫式密封件。迷宫式密封件中的间隙被设计成使得液体水可以被主动地带走，为此目的的迷宫式密封件至少设计成具有螺旋形式的通道（14,17,18）和/或楼梯本发明还涉及具有这种泵的燃料电池系统。
