FIELD: machine building.
SUBSTANCE: actuator for a blowing pipe is proposed, which has the possibility of performing in axial direction of back-and-forth movements and at the same time actuation. A longitudinally extended flexible rod element is provided, which is directed with several turns along a screw line about the machine element having the shape of a rod, which has the possibility of being operated in both directions. Angle of elevation of turns a rod element on the machine element having the shape of a rod can be changed due to possibility of variation of the distance between supply and discharge area of the rod element on the machine element having the shape of a rod.
EFFECT: enhanced operating reliability.
