HYDRAULIC VIBRATING SUPPORT Russian patent published in 2012 - IPC F16F9/53 F16F5/00 

FIELD: machine building.

SUBSTANCE: hydraulic vibrating support includes housing (1) with working chamber (3), compensation chamber (10) and metal partition wall (5), which is filled with electrorheological damping fluid. Working chamber (3) is restricted with supporting plate (4) and elastic shell (2). Compensation chamber (10) is restricted from below with corrugated membrane (11). In partition wall (5) there made are orifice holes (12) and intermediate cavity (6), in which pack of piezoelectric plates (7) fixed by means of elastic corrugations (8) to orifice holes (9) is arranged. Gas chamber (13) is separated from compensation chamber (10) with corrugated membrane (11), restricted from below with tray (14) and filled with partial mixture of gases with close temperatures of phase transitions of the second order.

EFFECT: improving damping characteristics of hydraulic support in the whole operating range of frequencies and damping of impact loads.
