Abstract: A multi-spring mechanical actuator includes a first spring having a first spring constant and a second spring having a second spring constant different than the first spring constant, wherein a load actuator is configured against the first spring under one loading condition and against a spring differential between the first spring and the second spring under a different loading condition.

Abstract: In view of the above, there has been described a load compensator including one or more tension spring assemblies that are contained within a tubular housing when tension from a load is applied to the tension spring assemblies. When the load compensator includes more than one tension spring assembly, the tension spring assemblies are mechanically connected to each other in series and stacked in-line with each other in the housing. In a preferred construction, each of the tension spring assemblies includes elastomeric tension elements mounted between two disks, and the tubular housing includes a tube having threaded ends and caps that screw onto the tube.

Abstract: The invention relates to a vibration isolator comprising a canister which ends are closed by end caps and a shaft able to move inside the canister, wherein the shaft comprises a piston-like shaped part for separating the canister in two parts: the first part being defined between the piston-like shaped part of the shaft and the first end cap, and comprising at least one resilient and damping element able to be compressed by a compression movement of the shaft on a first nominal stroke; the second part being defined between the piston-like shaped part of the shaft and the second end cap, and comprising at least one resilient and damping element able to be compressed by a tension movement of the shaft on a second nominal stroke; the tangential stiffness of the vibration isolator being, on at least one part of the first nominal stroke of the shaft, at least twice as lower as its tangential stiffness on the entire second nominal stroke of the shaft.

Abstract: A suspension strut having a piston tube containing a floating piston, slidable within a cylinder tube. A collar is fixed to the inner surface of the cylinder tube and contains a tapered wear ring. As the strut expands by extending the piston tube relative to the cylinder tube, the tapered wear band slides over valve orifices in the outer surface of the piston tube, gradually cutting off fluid flow from the annular space between the two tubes into an end cavity of the strut, thus increasing damping and reducing the likelihood of metal to metal contact at full strut extension. This reduces shock loads on the strut for smoother vehicle operation and increased component life.

Abstract: A hydraulic accumulator for providing pressurized fluid for a hydraulic system, includes a cylinder, a piston movably disposed in the cylinder defining a space in the cylinder on one side of the piston for pressurized fluid, and a mechanical spring device connected to the piston for generating pressure in the pressurized fluid.
