This invention relates to a damper device. Said damper device comprises a first impact energy absorbing member formed with an orifice for a liquid fluid in a cylinder to pass therethrough when said fluid is compressed so as to attenuate an initial force of impact by the viscous resistance of the flu...

| description | This invention relates to a damper device. Said damper device comprises a first impact energy absorbing member formed with an orifice for a liquid fluid in a cylinder to pass therethrough when said fluid is compressed so as to attenuate an initial force of impact by the viscous resistance of the fluid passing through said orifice, a second impact energy absorbing member controlled by said first impact energy absorbing member to produce frictional resistance between an outer surface of said second impact energy absorbing member and an inner wall surface of the cylinder for further attenuating the force of impact, a third impact energy absorbing member made of a compressible material and disposed in the cylinder for continuously attenuating the force of impact by a back pressure of the fluid in the cylinder produced by said first impact energy absorbing member, and a fourth impact energy absorbing member cooperating with said first and third impact energy absorbing members for further absorbing and attenuating the residual force of impact. |
