Abstract
The invention relates to a motor-driven pump unit, in particular for antilock systems of motor vehicles, with an electric motor that is arranged on one side of a pump unit and an electronic unit that is arranged on another side of the pump unit and fastened thereto. The main aspect of the invention is that means are provided for an axially movable attachment and contacting of carbon brushes in connection with an axial installation of the unit. In this way, the individual components of the unit can be assembled axially in a simple manner and at low cost. In addition, the unit requires very little space.
