FIELD: liquid-and-gas ejectors. SUBSTANCE: nozzle includes passage having inlet part narrowing in way of flow and outlet part. Surfaces of inlet and outlet parts are engageable forming sharp edge. According to another version, surface of narrowing part and outlet part of passage are engageable by means of intermediate surface whose generatrix has form of curve at curvature radius not exceeding 0.5 mm. EFFECT: minimization of energy losses in nozzle. 10 cl, 6 dwg |
