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

FIELD: machine building.

SUBSTANCE: pneumatic flexible element contains main flexible element (1) consisting of rubber-cord casing (RCC) (2), working (3) and additional (4) reservoir and of partition (5) set between them with electro-magnetic valve (EMV) (6), and auxiliary flexible element (7) consisting of auxiliary RCC (8), auxiliary working (9) and additional (10) reservoir and auxiliary partition (11) set between them with EMV (12). Main flexible element (1) is enclosed in first cylinder cartridge (13). Auxiliary flexible element (7) is enclosed into second cylinder cartridge (16) coaxial to first cylinder cartridge (13) and installed in orifice (14) of first cylinder cartridge (13). Both additional reservoirs (4) and (10) are rigidly interconnected by means of hollow rod (22) connecting the reservoirs continuously. Auxiliary additional reservoir (10) is made in form of third cylinder cartridge (18) along its lower ends having centring rollers (19) contacting internal surface of second cylinder cartridge (16). Orifice (23) connecting cartridge with atmosphere is made in a bottom of second cylinder cartridge (16). EMV (6) and (12) are connected to control unit (27).

EFFECT: increased damping qualities and simplified design.
