Abstract

Изобретение относитс  к судостроению и позвол ет повысить эффективность водометного движител . Водометный движитель содержит рабочее колесо 2 с полой ступицей (С) 7 и спр мл ющий аппарат 4 с. С 5. Между С 7 к С 5 имеетс  лабиринтовое уплотнение 8. За спр мл ющим аппаратом 4 установлено поворотное сопло, состо щее из корпуса 10 и обтекател  (О) 11. На торце. С 5 жестко закреплен Г-образный патрубок (П) 16. В О 11 установлен П 19. П 16 и П 19 подвижно соединены между собой, сообща  полость С 5 с окружающей Средой за срезом сопла. 1 ил.FIELD OF THE INVENTION The invention relates to shipbuilding and makes it possible to increase the efficiency of a jet propulsion unit. The jet propulsion unit comprises an impeller 2 with a hollow hub (C) 7 and a spraying apparatus 4 s. C 5. Between C 7 and C 5 there is a labyrinth seal 8. Behind the spraying apparatus 4, there is a rotary nozzle consisting of a housing 10 and a fairing (O) 11. At the end. C 5 is rigidly fixed L-shaped nozzle (P) 16. In O 11 installed P 19. P 16 and P 19 movably interconnected, together with the cavity C 5 with the surrounding environment for the nozzle section. 1 il.
