FIELD: machine building.
SUBSTANCE: invention relates to gas compression system including inlet guide vanes unit. Said inlet guide vanes unit has multiple guide vanes to make a radial structure around central axis to revolve about axes orthogonal to central axis. Said inlet guide vanes unit has multiple vane shafts, each being connected with appropriate inlet guide vane to revolve therewith about appropriate orthogonal axis. Said inlet guide vanes unit has extra drive shaft connected directly with one of vane shafts to drive the latter and the other vane shafts. Besides, said inlet guide vanes unit has rotary actuator engaged with drive shaft to revolve it.
EFFECT: decreased overall dimensions, simplified design.
