Abstract

See full text

A governor includes a housing, a pulley, a belt, a first flyweight, and second flyweight. The housing defines a housing cavity. The pulley is disposed at least partially within the housing cavity. The belt is in contact with the pulley. The belt is operable to rotate the pulley at a rotational speed. The first and second flyweights are pivotably connected to the pulley, and are biased towards one another. At least a portion of the first and second flyweights are operable to move away from the pulley when the rotational speed of the pulley is increasing toward a predetermined threshold rotational speed. The first and second flyweights are operable to contact the housing, and thereby transmit rotational energy to the housing, when the rotational speed of the pulley is equal to at least the predetermined threshold rotational speed.
