Abstract

The distributor comprises a rotatably mounted rotor, which has close to its axis of rotation a first electrode and has at its end that is remote from the axis of rotation a second electrode, which is connected by an electric line to the first electrode. The distributor also comprises a housing, which is closed by a cap, which is provided on its inside peripheral surface with a plurality of peripherally spaced apart fixed electrodes for cooperating with the second electrode of the roto. The cap is further provided on its inside surface with a center electrode, which terminates at a distance from the first electrode of the rotor to form a spark gap therewith. To form a positive joint with the cap the embedded portion of the center electrode has a non-cylindrical peripheral surface, which is rounded and free of any edge.
