PNEUMATIC FLEXIBLE ELEMENT Russian patent published in 2011 - IPC F16F9/04 

FIELD: machine building.

SUBSTANCE: pneumatic flexible element consists of main flexible element (9) containing rubber-cord shell (1), working (2) and additional (3) tanks and partition (4) installed between them. In partition (4) there is made calibrated orifice (5) and orifices (6) overlapped with freely lying diaphragm (7) at a rebound stroke. Auxiliary flexible element (11) includes auxiliary rubber-cord shell (12), auxiliary working (13) and additional (3) tanks and auxiliary partition (14) positioned between them. In auxiliary partition (14) there is made calibrated orifice (15) and orifices (16) overlapped with freely hanging diaphragm (17) at a compression stroke. Working tanks of main (9) and auxiliary (11) flexible elements are encased into external stationary cylinder cartridge (10) inside of which there is inserted an internal movable cylinder cartridge functioning as additional tank (3) of main (9) and auxiliary (11) flexible elements. Row of guiding slots (19) is made in the central part of external stationary cylinder cartridge (10); a damped object is rigidly tied with the internal movable cylinder cartridge by L-shaped poles.

EFFECT: simplified design at maintaining stability of damping properties.
