ターピッの駆動速度制御弁。A drive speed control valve incorporated in a driving device for a dental air turbine that supplies compressed air from a compressed air source to a handpiece through an air supply pipe, and provided in the middle of the air supply pipe, the valve having an air flow path 11; A vertically slidable plunger 12 that can vary the effective cross-sectional area of the flow passage 11, a spring 13 that presses the plunger 12 downward, and a spring 13 that slides the plunger 12 up and down and positions it appropriately. A valve body 1 including a coil 14 that generates a magnetic field for stopping the valve, and a drive circuit 2 connected to the coil 14.
The electric current and current flowing through the coil 14 can be varied by the drive circuit 2, and the vertical position of the plunger 12 can be changed appropriately by the magnetic field generated thereby, and as a result, the effectiveness of the flow path 11 can be changed. A driving speed control valve for a dental air turbine, characterized in that the amount of driving air supplied to a handpiece is controlled by changing the cross-sectional area.
