Abstract

A centrifugal governor is proposed which has particular applicability to the rpm-dependent variation of ignition or injection timing in internal combustion engines. The centrifugal governor is comprised primarily of a driving shaft and a driven shaft and of a governor disc removably connected with the driven shaft. One eccentric pair is situated on the governor disc for each flyweight; each eccentric pair is coupled with the driven shaft, which serves as the camshaft of an injection pump and may be rotated by the flyweights articulated on the eccentrics in order to vary the mutual rotary position of both shafts.
