Beschreibung
Zusammenfassung:	FIELD: oil industry. ^ SUBSTANCE: air drive comprises worm reduction gear, fluidic motor with the connecting pipe provided on the housing of the motor, shaft and rotor with nozzles inside the housing of the fluidic motor, reduction gear of the fluidic motor with cylindrical gearing, electropneumatic control device with air-operated valve, and device for control of the position of the output shaft. The housing of the reduction gear of the fluidic motor is provided with the connecting pipe for supplying gas. The rotor of the fluidic motor is provided with additional axial passages and additional nozzles so that the rotor can be set in reversing rotation. The second face of the shaft of the fluidic motor is provided with the axial passage with radial openings for supplying gas to the additional passages in the rotor. The electropneumatic control device is provided with additional air-operated valve and connecting pipe which is in communication with it. The connecting pipe is coupled with the connecting pipe on the housing of the reduction gear of the fluidic motor through the gas discharging duct. The device is made for permitting the supplying connecting pipe to be in communication with the gas pipeline. ^ EFFECT: enhanced reliability. ^ 6 dwg
