PIVOT DAMPER Russian patent published in 2012 - IPC F16F9/12 

FIELD: machine building.

SUBSTANCE: proposed damper comprises receiving channel with bore on one end and lower section on opposite end. Proposed pivot element may revolve and be retained in open end section of receiving channel. Piston is arranged between pivot element and lower section. Retainer prevents piston turn and makes it stop at preset initial position. Displacement lock inhibits piston displacement beyond the limits of the second position. Drive comprises displacing means and cam mechanism. Said drive moves piston from first position toward second position. In compliance with first version, piston gets released from stop state caused by retainer to turn between initial position and end position. In compliance with second version, pivot element turns between second and third positions relative to piston in initial position when the latter stays in second position.

EFFECT: ruling out piston displacement beyond second position.
