Abstract:
1. A fluid-elastomeric damper assembly operable for damping a relative motion between a first structure and a second structure, the fluid-elastomeric damper assembly comprising: a plurality of elastomer seals coupled to the first structure, wherein the first structure and the plurality of elastomer seals define an external fluid-elastomeric chamber operable for containing a fluid; an internal pumping mechanism, said internal pumping mechanism including a first substantially fluid-filled internal pumping chamber, a second substantially fluid-filled internal pumping chamber, at least one internal pumping orifice between said first substantially fluid-filled internal pumping chamber and said second substantially fluid-filled internal pumping chamber and at least one fluid moving internal pumping piston, said least one fluid moving internal pumping piston for forcing said fluid through said at least one internal pumping orifice, said internal pumping mechanism disposed within said external fluid-elastomeric chamber distal from said elastomer seals with said first substantially fluid-filled internal pumping chamber, said second substantially fluid-filled internal pumping chamber, and said at least one internal pumping orifice separated from said external fluid-elastomeric chamber, with said first substantially fluid-filled internal pumping chamber and said second substantially fluid-filled internal pumping chamber in fluid communication with said external fluid-elastomeric chamber, wherein the internal pumping mechanism is grounded to the first structure and driven by the second structure, and wherein the at least one fluid moving internal pumping piston forces said fluid through said at least one internal pumping orifice between said first substantially fluid-filled internal pumping chamber and said second substantially fluid-filled internal pumping chamber; and wherein said relative motion between said first structure and said second structure is operable for pumping the fluid through said at least one internal pumping orifice.
