Title: Centrifugal advance device for an ignition distributor
IPC: F02P5/06
Filed: 1971-07-06
Abstract: A centrifugal advance device for an ignition distributor for an internal combustion engine wherein there are provided two main flywheel masses and two auxiliary flywheel masses. The main masses are each pivotable on a pin mounted on a plate which is connected to a drivable shaft and the auxiliary masses are coupled to the main masses. These masses are adapted on rotation of said shaft to displace a plate connected to a cam which is adapted to actuate a contact-breaker arm for obtaining a variation in the timing of the spark. The auxiliary masses are arranged to move the main masses in their angular displacement during a first stage of variation corresponding to a lower region of engine speed. After the engine speed has passed through this lower region, two abutments fixed to the plate connected to the control shaft prevent further angular movement of the auxiliary masses and main masses, thus providing an intermediate region of engine speed during which the timing of the spark does not vary. As the engine speed increases still further into an upper region spring means acting on said masses are overcome to permit further angular movement of the main masses and thus further angular movement of the plate connected to said cam.
