TURBINE PLANT STATOR CONTAINING STAGE OF OUTLET GUIDE VANES BROUGHT INTO ACTION BY MEANS OF ROTARY RIM WITH AUTOMATIC ALIGNMENT; COMPRESSOR WHICH CONTAINS ABOVE DESCRIBED STATOR, AND TURBINE PLANT Russian patent published in 2012 - IPC F01D17/16 F04D29/56 F01D9/02 

FIELD: machine building.

SUBSTANCE: stator of turbine plant includes casing, stage of guide vanes with adjustable setting angles, actuating rim and a guide. Guide vanes are moved by means of the actuating rim installed on outer side of casing and connected to vanes by means of rods. Guide projects above external surface of casing and is rigidly fixed on the latter. Three blocks of rollers to move along the guide are located in circumferential direction of rim at equal distances from each other. Each block of rollers is connected to rim so that each block of rollers is directed radially relative to the rim. Each block of rollers includes at least two rollers interacting with the guide, and each roller is installed on radial axis installed immediately on the rim. Other inventions of the group refer to compressor and turbine plant, which contain the above stator.

EFFECT: inventions allow providing alignment of the rim relative to casing without sufficient complication of stator design.
