FIELD: machine building.
SUBSTANCE: diffuser having possibility of jet executive control comprises longitudinal axis, diffuser inlet, diversion socket having diffuser wall, opening in diffuser wall located near diffuser inlet, curvilinear channel located near opening and independent auxiliary compressor unit. Independent auxiliary compressor unit is connected to curvilinear channel. Curvilinear channel is curved convexly relative to longitudinal axis and is intended for introduction of additional jet in opening along diffuser wall for maintenance of additional jet along this wall with application of floatation effect. Curvilinear channel and opening are arranged with the possibility of additional jet introduction via opening at controlled first angle relative to diffuser wall and second angle relative to axial flow passing along diffuser longitudinal axis, for provision of maximum efficiency of diffuser.
EFFECT: increased efficiency of diffuser.
