摘要： A governor device for rotary grinders and the like is disclosed. The device prevents the dangerous overspeed of the grinder by throttling air to the motor as the grinder speed approaches overspeed. Throttling action is accomplished by means of allowing a resilient split ring or segment to expand radially out against air inlet orifices by means of centrifugal force. The split ring is assisted outwardly by means of an auxiliary mass means disposed within radially extended slots of an internal cage means.
