Abstract

Regular grooves (7) are cut into the surface of the collector ring in order to be connected with channels (6) conveying the coding gas in the axial direction. The collector ring consists of a hub insulated but mechanically fixed upon a shaft (1) and a ring flange (5) extending in the axial direction along both sides. The grooves (7) are connected to the medium carrying channels (6) via cuttings (8) in the form of circular cross-sections penetrating through the ring flanges (5) in the radial direction. The connection is thus made between the shafts (1) outer diameter and the ring flange (5) inner diameter.
