METHOD OF COMPENSATING FOR DISPLACEMENTS IN PNEUMOHYDRAULIC SYSTEM LINES Russian patent published in 2009 - IPC F16L51/00 

FIELD: aerospace engineering.

SUBSTANCE: invention relates to aerospace engineering, particularly, to method of compensating for displacements in pneumohydraulic system lines. In compliance with this invention, proposed method consists in that, prior to operation, the device compensating element is subjected to expansion or compression, and/or bending in direction opposite to the vector of resultant rated value of relative displacements till required design parametres of the said compensating element. Then, the compensating device, its state changed, into pneumohydraulic system line. Note that aforesaid vector of resultant design value of relative displacements is obtained by geometrical addition of maximum vectors of relative displacements in every coordinate plane, aforesaid displacements being caused by whatever force, thermal and service effects acting on the line at one and the same time interval.

EFFECT: compensation of relative displacements in conditions of limited space.
