FIELD: engines and pumps.
SUBSTANCE: nozzle comprises body with insert in the form of cylindrical spring and guide channel arranged in its area, and nozzles for abrasive and compressed air supply into guide channel. Guide channel is arranged as cone-shaped, narrowing to the side of its outlet section. In body, axisymmetrically to guide channel, bush is installed with openings that communicate guide channel with nozzles for supply of abrasive and compressed air. Openings that communicate nozzle for supply of compressed air and cavity between insert and wall of guide channel are arranged along helical line relative to axis of guide channel. Section of body with guide channel is arranged in the form of separate part with the possibility of its longitudinal displacement and fixation.
EFFECT: increased wear resistance of insert, prolonged service life of insert and nozzle.
