ABSTRACT:
A centrifugal force adjusting mechanism for contact breakers of internal combustion engines, in which the main structural parts which include a drive shaft, an intermediate member and a contact breaker disk are rotatable with respect to one another in both directions of rotation against spring force by flyweights; the flyweights are thereby provided with two separate abutment surfaces which are so arranged in relation to the axis of rotation of the flyweights and the axis of rotation of the main structural parts that they are supported at counter surfaces of the main structural parts, on the one hand, in the direction of rotation of the drive shaft and on the other, opposite the direction of rotation of the drive shaft, whereby within a first rotational speed range of the drive shaft, the abutment surfaces and counter surfaces abut at one another in one direction of rotation whereas the other abutment surfaces and counter surfaces become operative only within a further rotational speed range.
