Abstract
Centrifugal advance device for ignition distributor of internal combustion engine, which includes a centrifugal regulator equipped with counterweights, which, dragged in rotation by the distributor shaft, angularly displaces the solidary plate of the cam that drives the moving contact breaker, for obtaining ignition point variation curves and in particular staircase curves with three variation stages, that is, a first and a third stage, located respectively in the lower and upper areas of the number of turns, and a second stage in which the ignition point does not vary, characterized in that it includes two centrifugal masses supported so that they can pivot on a support plate integral with the drive shaft and subjected during the first stage of variation to the action of a first spring that acts against the angular displacement of the cam's sole plate, a lever mounted so that it can rotate in the support plate integral with the drive shaft with which it is elastically coupled during the first stage of variation, under the conjugated action of an adjustable stop attached to said support plate and a second spring subjected to a certain initial tension, a first support member attached to the lever and with which a second support member integral with the cam plate comes into contact, at the time corresponding to the end of the first variation stage, at which point the tensions of the springs are added and oppose the centrifugal forces and therefore the angular displacement of the cam plate, to obtain the second stage of variation, until the centrifugal forces that increase, due to the increase in the number of turns, exceed the stresses of these springs and determine, by means of a new angular displacement of the cam plate that acts against the lever that rotates around its articulation axis. n, under the tension of said plate, the third stage of variation.
