LIQUID FUEL ROCKET MOTOR (LFRM) CAMERA OSCILLATION ASSEMBLY Russian patent published in 2014 - IPC F02K9/66 

FIELD: motors and pumps.

SUBSTANCE: assembly for camera oscillation in one plain comprising the camera installed by cone pins in antifriction bearings in yokes, fixed on its power frame, and assembly of hoselines, where according to the invention bellows and the hoselines are integrated in two hoseline units (HLU), fixed by their non-moving brackets to yokes located along both sides of the camera along the oscillation pin, and hoselines, interacting using the movable brackets, meanwhile the movable HLU bracket of the gas path by its thimble contacting from the one side with the cylindrical surface of the thread bush, screwed into the cone pin of the camera, and from the other part has the yoke contacting through the spherical joint with the thimble of non-moving flange of this HLU, meanwhile in holes of movable and non-moving brackets the bushes are installed, to which the bellows tips are fixed, and movable HLU bracket , located from the other side of the camera, by the yoke interacts with overhung axle of the cone pin of the camera designed with two side plane surfaces, meanwhile between the yoke of movable HLU bracket and axle in their holes the pin is installed.

EFFECT: improvement of reliability of operation, uniform bending of flexible elements, improvement of precision of installation of a geometrical centreline of the camera, decrease of critical dimensions of the oscillation assembly.
