FLEXIBLE JOINT OF ANGULAR AND LINEAR DISPLACEMENTS (OPTIONS) Russian patent published in 2018 - IPC F16L51/02 

FIELD: rocket technics.

SUBSTANCE: invention relates to rocket and space technology and is used to compensate for linear and angular movements of pipelines in pneumatic-hydraulic lines during installation and operation. Flexible joint of angular and linear movements contains a bellows, flanges, a body and a limiter of angular and linear displacements. Body is made in the form of two cylinders of a larger and smaller diameter, the cylinders being connected to each other telescopically and interacting with each other by means of a spherical projection on a cylinder of smaller diameter. At the end of the cylinder with a larger diameter, an annular projection is formed. Radius of the spherical projection of the cylinder of smaller diameter is equal to the radius of the inner surface of the cylinder of a larger diameter. Symmetry axis of the spherical projection of a cylinder of smaller diameter coincides with the axis of symmetry of the bellows. According to a second embodiment of the compensator, the housing is mounted inside the bellows and fixed to the flanges by pylons or directly on the flanges.

EFFECT: increase the strength and parametric reliability of the compensator.
