| 摘要 |
The present invention relates to a distributor for an electric D.C. machine comprising a commutator associated with two elastically deformable conductor rings, each forming a wing placed above the commutator on the path of at least one roller carried by a moving element, each roller establishing, by elastic deformation of the corresponding ring, a mobile electrical contact between said ring and the commutator. The invention is more particularly applied to rotary machines.
