DAMPER CARTRIDGE (3 VERSIONS) Russian patent published in 2017 - IPC E01F15/14 

FIELD: machine engineering.

SUBSTANCE: damper cartridge comprises a front baffle, a rear wall and an inertial reducer section. The section of the inertial reducer is defined by flat vertical plates. The section of the inertial reducer according to one version is formed by twin, vertically arranged non-contiguous sheet elements with zigzag folds oriented in opposite direction relative to each other. Each end of each element with the zigzag fold is bent outwards to form a through channel parallel to the axis of the damper cartridge. The vertical plate is fixed in front of the rear wall. The section of the inertial reducer according to the second version is made in the form of a perforated through box oriented horizontally relative to the through opening. Perforation is made on each of four sides of the box, and at the folds, at that the perforation at the folds enters on both adjacent sides of the box. The vertical plate is fixed in front of the rear wall. The damping cartridge according to the third version consists of two types of sections of inertial reducers: the inertial reducer section formed by twin, vertically arranged non-contiguous sheet elements with zigzag folds oriented in opposite direction relative to each other, wherein each end of each element with the zigzag fold is bent outwards to form a through channel parallel to the axis of the damping cartridge, and a section of the inertial reducer made in form of the perforated through box oriented horizontally relative to the through opening, at that the perforation is made on each of the four sides of the box, and at the folds, wherein the perforation in the folds enters on both adjacent sides of the box. Flat vertical plates define each section of the inertial reducer. In all versions, the damping cartridge can contain 1+n sections of each type of the inertial dampers, while the flat vertical plates define each section of the inertial reducer.

EFFECT: oscillation damping.
