    Abstract: A hydraulic actuator includes a shock absorber and a control system that is separate from the shock absorber and which generates damping loads for the hydraulic actuator. The control system generates the damping load by using a pair of variable valves, a pair of check valves, an accumulator, a pump/motor and a flow controller. The forces are generated in all four quadrants of compression/rebound and active/passive. A device which recuperates the energy generated by the hydraulic actuator can be incorporated into the hydraulic actuator to generate energy in the form of electrical energy.

    Abstract: There is disclosed a damping coefficient switching-type hydraulic damper that may automatically switch a damping coefficient without needing supply of energy from the outside at all, and also may always surely exert an energy absorption capacity greater than that of a typical hydraulic damper. While a piston (3) is moving in a direction A, a mechanical drive means (30) composed of a straight gear (31) and a crank mechanism (31) allows an on-off control operation valve (11), that is, a flow regulating valve (10) to be placed in a closed state, and a damping coefficient is switched to a maximum value Cmax. When a movement of the piston (3) is turned in a direction B at a left-side maximum point of amplitude, the mechanical drive means (30) works to once open the flow regulating valve (10) to perform elimination of a load, so that the damping coefficient is switched to a minimum value (Cmin). When the piston (3) further moves in the direction B, the mechanical drive means (30) works to close the flow regulating valve (10) again, and the damping coefficient is returned to the maximum value (Cmax). Similar working to the above is also applied to a right-side maximum point of amplitude, and seismic response control is attained with repetition of the above operations.

    Abstract: A leveling valve for discharging and supplying air from and to a plurality of utilization elements comprises a valve disc arrangement configured to direct air between a source of pressurized air, an exhaust port, and the utilization elements. The valve disc arrangement comprises a first and a second valve disc, which are rotatable with respect to each other such that the valve is switchable between multiple switching positions, and, in some switching positions, either the source of pressurized air or the exhaust port are in fluid communication with the utilization elements. The valve discs provide a stepped increase in flow cross-section in a respective flow path to or from the utilization elements. The stepped increase is dependent on the angle of rotation between the valve discs.
