FIELD: engines and pumps.
SUBSTANCE: set of invention relates to rotary vane control mechanisms and can be used in aircraft turbomachine compressor guide apparatus to control inclination of guide apparatus guide vanes, and in stationary gas turbine engines. Proposed control device comprises tie rod, links including coupling sleeve arranged in driving ring and pin with its one end connected with tie rod and another end arranged in coupling sleeve, and elements to arranged tie rod on the pin of vane to be controlled. In compliance with this invention, coupling sleeve is arranged off center, aforesaid pin is pivoted onto tie rod, off center relative to the pin part fitted into coupling sleeve. Note also that proposed device can be fixed in required position with respect to relative arrangement of the pin and coupling sleeve in driving ring.
EFFECT: higher accuracy of rotary vane mounting, higher reliability and efficiency.
