Patent ID: 8740200

Claim:
A fluid-elastomeric damper including: a nonelastomeric housing; at least a first nondynamic elastomer seal coupled to the housing with the housing and the at least first nondynamic elastomer seal providing an outer fluid-elastomeric chamber containing a damper fluid for submerging an internal pumping mechanism with said outer fluid-elastomeric chamber and said fluid-elastomeric damper containing said damper fluid without a dynamic seal, said internal pumping mechanism disposed within the fluid-elastomeric chamber, with said housing coupled to a first structure, said first elastomer seal coupled to a second structure, said second structure movable relative to said first structure, said internal pumping mechanism including a piston structure housing coupled to the second structure and a piston structure disposed within the piston structure housing wherein said piston structure housing comprises a first damper fluid-filled chamber and a second damper fluid-filled chamber, the first damper fluid-filled chamber and the second damper fluid-filled chamber in communication via a damper fluid restriction with said first damper fluid-filled chamber and said second damper fluid-filled chamber isolated from said at least first non-dynamic elastomer seal.
