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

FIELD: machine building.

SUBSTANCE: pneumatic flexible element is complex and consists of two flexible elements: main flexible element (7) with working reservoir (2) and additional reservoir (3) and auxiliary flexible element (12) with auxiliary working reservoir (14) and auxiliary additional reservoir (15). Both flexible elements are interconnected by means of rigid connection of upper end (11 of additional reservoir (3) with base (19) of auxiliary additional reservoir (15). Each flexible element is equipped with a damping device consisting of a gate electro-magnetic valve controlled with control system (22). A damped object is tied with the pneumatic flexible element by means of poles (20) connected to additional reservoir (3). Both gate electro-magnetic valves (6, 18) are connected to valve control system (22) containing serially coupled: a converter of object transfer, an object velocity signal shaper, a control division unit, key control units, and power keys for connection of coils of gate valves electro-magnets (6,18) to power source.

EFFECT: increased damping properties at high frequency constituents of external effect with low amplitudes.
