To provide a driving device in which wear debris of a commutator is prevented from leaking out of a housing and reaching, for example, a hydraulic pump driven by the driving device, or an optional eccentric bearing, in a simple and cost-effective manner.SOLUTION: A driving device 1, in particular, for a hydraulic pump 2 of a braking system of an automobile includes: a rotor shaft 6, supported in a housing 5, for supporting a rotor 8; and a commutator 9 arranged in the housing; and at least one commutator brush 12, in which the commutator is held by a brush support 11. The commutator brush cooperates with a commutator ring 10 arranged non-rotatably on the rotor shaft. The brush support has a seal ring 13 assigned to the commutator. The seal ring is arranged coaxially with the rotor shaft and cooperates with the rotor shaft for hermetic sealing.SELECTED DRAWING: Figure 1

    【課題】整流子の摩耗破片がハウジングから漏れ出し、例えば駆動装置によって駆動される液圧ポンプに、またはオプションの偏心軸受に達し得ることが簡単かつ低コストで阻止される駆動装置を提供する。【解決手段】ハウジング5において支持され、かつロータ8を支えるロータ軸6と、ハウジングに配置された整流子9とを備え、整流子が、ブラシ支持体11によって保持される少なくとも1つの整流子ブラシ12を有し、整流子ブラシは、ロータ軸上に回動不能に配置された整流子リング10と協働する、特に自動車のブレーキシステムの液圧ポンプ2のための駆動装置1。ブラシ支持体が、整流子に割り当てられたシールリング13を有し、該シールリングがロータ軸と同軸に配置されているとともに、ロータ軸と密封するように協働する。【選択図】図1
