DEVICE FOR JET WORKING OF SURFACE Russian patent published in 1997 - IPC

FIELD: power engineering. SUBSTANCE: device has carriage mounted on the base, drive with a screw pair, shaft with a nozzle head, and means for shifting the trajectory of the jet of working agent when axial movement of the shaft changes. The shaft and nut of the screw pair are mounted on the carriage. The nut is locked against rotation. The means for shifting jet has a system of stops that are movable and fixed in the direction of the axis of the motion to allow shifting of the nut with respect to the carriage when the direction of shaft changes and fixing a space between them. EFFECT: enhanced efficiency. 9 cl, 4 dwg
