Abstract
An apparatus has at least one pendulous member mounted on a rotor so as to be able to swing about an axis of pendular motion spaced at a distance from the center of inertia of the pendulous member. The pendulous member is pivotably mounted on its own axis of rotation parallel to the axis of pendular motion and situated substantially closer to the center of inertia of the pendulous member than to the axis of pendular motion.
