CONSTANT EFFORT DEVICE Russian patent published in 2022 - IPC F16L3/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to areas of technology where support and suspension devices are used to ensure a constant effort of interaction between movable and load-bearing structures and, in particular, is intended to connect sections of pipelines intended for transporting media under pressure with the corresponding load-bearing structures. The rod 2 with elements for attaching a movable structure with one end made rectangular in cross-section is placed in the counter hole of the plug 4 of the housing 1 of the device with a contour copying the contour of the section of the above-mentioned end of the rod 2, at the other end of the rod 2, a self-braking external thread is made, on which a cap nut 5 is screwed, at the end of which a rectangular through hole is made for the passage of the screw 6, in which the part passing through the specified hole has a cross-section, the contour of which copies the contour of the specified hole in the cap nut 5, at the same time, a non-self-braking thread is made at one end of the screw 6, placed in a threaded hole made in the end part of the rod 2 from the end opposite to the end of the rod 2, made rectangular in cross-section, and the cap nut 5 with its outer cylindrical surface contacts the inner cylindrical surface of the housing 1 of the device, and the spring 3 is located between the plug 4 of the housing 1 and the end of the cap nut 5 adjacent to the threaded part of the cap nut 5, and the self-braking and non-self-braking threads have different directions and the same steps and the end of the screw 6, located on the opposite side from the threaded end, is fixed in the axial direction, while the device is equipped with a lock 7 of the rod 2.

EFFECT: reduction in the dimensions of the device in the direction perpendicular to the movement of the rod.
