Three parameter viscous damper and isolator

A vibration damping and isolation apparatus, comprising:

• a shaft having an axis therethrough, said shaft having a first and second end;
• a first extension extending radially from said first end of said shaft, said first extension having a first fluid path therethrough;
• a second extension extending radially from said second end of said shaft, said second extension having a second fluid path therethrough;
• a piston having an axial bore coaxially positioned with said shaft to form a damping path therebetween, said piston having a flange extending radially therefrom for coupling the apparatus to a load;
• first primary bellows connected between said first extension and said flange for forming a first fluid chamber;
• second primary bellows connected between said second extension and said flange for forming a second fluid chamber, said first fluid chamber connected to said second fluid chamber by said damping path;
• first secondary bellows connected to said first extension and a first sealing member to form a third fluid chamber, said third fluid chamber connected to said first fluid chamber by said first fluid path;
• and
• second secondary bellows connected to said second extension and a second sealing member to form a fourth fluid chamber, said fourth fluid chamber connected to said second fluid chamber by said second fluid path.
