Patent ID: 7874407

Claim:
A magnetorheological fluid damping system, comprising: a hydraulic cylinder configured for at least partially disposing magnetorheological fluid therein, wherein the hydraulic cylinder includes first and second ends; a piston head disposed within the hydraulic cylinder, the piston head having first and second sides, wherein the piston head defines first and second chambers within the hydraulic cylinder, the first chamber being adjacent to the first side of the piston head, the second chamber being adjacent to the second side of the piston head, wherein the piston head is configured to be in sliding engagement with the hydraulic cylinder; a piston rod at least partially disposed within the hydraulic cylinder through the first side of the hydraulic cylinder, wherein the piston rod is operatively connected to the piston head on the first side; and a porous valve including at least one magnetorheological fluid pathway, wherein the porous valve includes first and second fluid connections, wherein the porous valve is configured to dampen the flow of the magnetorheological fluid between the first and second fluid connections in accordance with a magnetic field, wherein the first fluid connection is fluidly connected to the first chamber and the second fluid connection is fluidly connected to the second chamber, wherein the first fluid connection forms an internally threaded region configured to receive a hollow screw for securing at least one washer to a mesh, wherein the at least one magnetorheological fluid pathway is configured to at least partially direct the magnetorheological fluid flow through a porous media.
