<p>A high-voltage distributor for ignition systems of internal combustion engines has a cap (10) made of insulating material and a rotor (14) that rotates in a housing (11). A central electrode (12) and several fixed electrodes (13) are arranged in the cap (10) of the distributor. The rotor (14) of the distributor, which rotates synchronously with the camshaft of the internal combustion engine, establishes while it rotates around the axis of rotation (15) an electrical connection between the central electrode (12) and each of the fixed electrodes (13). To obtain a punctual contact between the central electrode (12) and the electrode (16) of the rotor, the rotor (14) of the distributor has a dome (20) concentric in relation to its axis of rotation (15) and which contains an axially arranged carbon brush (24). The carbon brush (24) has a convex bulge (25) on its front face that is pressed against the central electrode (12) by a compression spring (23) that rests on the electrode (16) of the rotor.</p> |
