A one-way circuit with one-way valves causes the damping medium to flow in the same direction of circulation when the piston rod plunges into the damper chamber and when it emerges therefrom. A first one-way valve on the piston allows the damping medium to flow from the second into the first chamber. A second one-way valve between the throttle valve and the second chamber allows the damping medium to flow from the throttle valve into the second chamber. | 2015-10-08 |
20150285327 | Multiphase Materials For Stress Wave Steering And Methods Of Providing Same - An exemplary embodiment of the present invention provides a method of achieving a desired attenuation pattern in a material when a force is applied incident at least a portion of the material. The method comprises providing a multiphase material in a decompressed state, the multiphase material comprising a matrix material, a first periodic lattice of first inclusions positioned with the matrix material, and a second periodic lattice of second inclusions positioned within the matrix. The first periodic lattice of first inclusions can have a first set of lattice characteristics, and the second periodic lattice of second inclusions can have a second set of lattice characteristics different than the first set of lattice characteristics. The method can further comprise selecting the first and second sets of lattice characteristics based on a desired stress wave attenuation pattern when a force is applied incident to at least a portion of the multiphase material. | 2015-10-08 |
