Zusammenfassung:	The utility model relates to an improved air gate motor steel ball type speed regulator which is characterized in that a drive member is arranged in an air gate. The inner hole of the air gate is glidingly matched with the outer circle of the drive member. The inner hole of the drive member and the drive shaft of a pneumatic motor are fixedly arranged. The drive member is provided with an arc-shaped groove in which a steel ball which can slide is arranged. A spring is abutted on the air gate and the drive member. When the pneumatic motor overspeeds, the steel ball overcomes spring force to drive the air gate, an air flow channel is decreased or cut off, the speed is regulated, and the safety is high. The utility model has the advantages of simple structure, and good manufacturability. The manufacturing cost is obviously reduced, and the performance is improved.
