DEVICE AND METHOD OF POSITIONING OF MACHINERY WITH VARIABLE GEOMETRY FOR TURBOMACHINERY USING HYDRAULIC CYLINDER WITH RELATIVE MEASUREMENT Russian patent published in 2014 - IPC F01D17/20 

FIELD: machine building.

SUBSTANCE: device for positioning of machinery with variable geometry for turbomachinery, controlled by the calculator and kinematics, while the named actuator comprises a movable construction fitted with a sensor for measuring of its elongation, and the named kinematics is connected by one of its ends with a place of engagement of the named movable construction, and the other end - with the place of equipment connection, while the place of connections moves under the action of the actuator along the stroke limited by a stop, and the kinematics is implemented as elastically deformed under the action of the actuator, when the place of connection is at the stop. The command for elongation generated by the calculator of the named movable construction is determined on the basis of elongation of the movable construction corresponding to the contact of the place of connection with the stop.

EFFECT: avoidance of wears occurring in kinematics, and identification of possible destructions in this kinematics.
