Apparatus for absorbing mechanical energy, in particular energy of very strong shocks

In apparatus for absorption of mechanical energy, particularly energy of very strong shocks, comprising two parts:

• an immobile cylinder and a mobile part inserted telescopically therein, said mobile part comprising one or more telescopically arranged movable cylinders each having a bottom and a piston inserted into the last of said telescopically arranged movable cylinders;
• the space within the immmobile cylinder and the movable cylinders being filled with media for absorbing energy of shocks and vibrations, the media in the immobile cylinder having the highest elasticity and the media in the last of the movable cylinders having the lowest elasticity and a viscous flow in the static state and a high elasticity in dynamic state;
• the improvement wherein at least one of the movable cylinders is provided with a mobile baffle dividing the same into two chambers, the first chamber being filled with a viscoelastic medium selected from the group consisting of polysiloxane polymers, liquid halogen-containing polymers, aliphatic alcohols and polyalcohols, and the second chamber being filled with a medium selected from said group compressed to a pressure higher than 1000 h Pa, such compression of the latter medium causing the medium in said first chamber to be maintained in a stressed state.
