FRICTION DEVICE FOR FORCE ADJUSTMENT AND FRICTION DAMPER INCORPORATING SAID DEVICE Russian patent published in 2012 - IPC F16F7/04 

FIELD: machine building.

SUBSTANCE: friction device comprises, at least, two elements 1, 5, one of which moves, or, potentially, may move relative to another one, driven by external force P. Relative displacement can cause relative displacement of two friction surfaces subjected to pressure forces to convert external force P into friction force and, thus, to adjust displacement of moving or potentially moving element. Pressure forces are created by pre-stressing appliances 17. Elements 1, 15 are designed to act on said pre-stressing appliances 17 to exploit developed effect of aforesaid relative displacement so as to reduced pressure forces. Friction damper of oscillations comprises aforesaid friction device.

EFFECT: possibility to adjust friction force irrespective of fraction factor of friction surfaces.
