FIELD: manufacture of hydraulic turbines, Pelton turbines in particular. SUBSTANCE: nozzle has body 1 where capsule with rod and piston 5 of servomotor arranged in it is secured. Nozzle needle 6 is secured on rod 4. Nozzle has stem 7 for back coupling of servomotor rod with spool valve of rotational speed regulator which is engageable with rod 4 of servomotor through gear train consisting of toothed rack 10 secured on rod 4 and gear wheel fitted on back coupling stem 7. Such construction makes it possible to exclude bending stresses in stem 7, thus enhancing reliability of back coupling of servomotor rod with spool valve of rotational speed regulator. EFFECT: enhanced reliability. 2 cl, 2 dwg
