Abstract

An ingnition distributor for an internal combustion engine, more particularly, for a motor vehicle internal combustion engine having an electronic ignition system driven by a distributor shaft which, in turn, is driven by the engine and having a device for changing a phase relationship between the distributor shaft and a distributor rotor. A control disk is rotatably mounted on the distributor shaft and is rigidly coupled with the distributor rotor. The rotation of the distributor shaft is capable of being transmitted to the control disk by means of at least one spring. An electromagnet is provided between the two poles of which the control disk is rotated, with the electromagnet forming with the control disk an anti-current brake. An electronic phase control is provided for regulating an excitation current of the electromagnet in accordance with a difference between the actual and set value of the phase displacement in dependence upon operating parameters of the internal combustion engine.
