CENTRIFUGAL GOVERNOR

The invention concerns a centrifugal governor comprising a rotatable driving member, a plurality of equi-angularly spaced apart flyweights which have driving connections with the said driving member so as to be rotated by the latter, at least portions of the flyweights being movable radially outwardly under centrifugal force, a rotatable and axially movable driven member having driving connections with the flyweights so as to be rotated thereby and so as to be moved axially thereby in a given axial direction when the flyweights move radially outwardly, the driving and driven members being coaxial, and means for urging the driven member in the opposite axial direction, all the said driving connections comprising relatively non-slidable parts which roll over each other during axial movement of the driven member in the said given axial direction.
