COMPENSATOR OF ANGULAR MOVEMENTS OF PIPELINES Russian patent published in 2019 - IPC F16L51/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in pneumatic-hydraulic systems. Compensator comprises bellows, end flanges and hinge joint. Hinge joint consists of ring with four holes, two jaws, each of which has two lugs with holes, and four axes of hinge joint. Lugs of jaws are connected with ring by means of axes of hinge joint. Flexible element (one or several) made in form of smooth-wall tube is installed on compensator. Tube has straight section fixed at distance from axes of hinge joint in their common plane by means of bracket on fixed ring. One end of said rectilinear section, passing along radius of one of axes of hinge hinged joint, changes into rectilinear section fixed through bracket on end flange, and other end, passing along radius of other axis, changes into rectilinear section fixed through bracket on opposite end flange. All rectilinear sections are parallel to lengthwise axis of compensator and are fixed in brackets through bushings, enveloping tube by outer diameter, providing freedom of movement of tube along longitudinal axis of compensator.

EFFECT: provision of angular compensation of displacements in two planes of several pipelines.
