ELECTRO PNEUMATIC DAMPER Russian patent published in 2013 - IPC F16F9/04 F16F6/00 

FIELD: machine building.

SUBSTANCE: proposed damper comprises holder 1 and punch 2 interconnected by elastic resilient element 3. Solenoids 4, 5 are arranged coaxially therewith and with each other. Composite core 6 is rigidly connected with holder. Two magnetic parts 7, 8 of said core are arranged at equal distance between solenoid coils in the position of static equilibrium. Nonmagnetic spacer 9 is arranged between solenoid magnetic parts. Solenoid coils are connected to power supply via control units power switches 10. Windings 11, 12 of object displacement transducer arranged inside solenoid coils and aligned therewith are connected to control unit.

EFFECT: higher efficiency of damping and smooth run.
