FIELD: finishing and strengthening parts in different branches of industry. SUBSTANCE: ejector has housing in which two gas nozzles with mutually parallel axes are arranged. Said nozzles have common gas supply system (through manifold). In housing of ejector two mixing chambers are arranged coaxially relative to gas nozzles. Inner cavity restricted by housing is communicated with mixing chambers and it is connected with union for feeding hydraulic mixture. Each mixing chamber is provided with diffuser whose opening is shifted to side of axis of adjacent mixing chamber. EFFECT: enhanced intensity and uniformity of treating parts, enlarged manufacturing possibilities of ejector. 3 cl, 3 dwg
