    Abstract: The present invention involves a fluid seal assembly of a pressured system for reducing static friction on a displacement rod of the pressured system. The assembly comprises a sealing member disposed on a surface of the pressured system. The sealing member is in circumferential engagement about the displacement rod to define a radial preload on the displacement rod forming a static friction thereon. The assembly further comprises an actuator attached to the sealing member and being configured to bend when the electric input is applied thereacross to displace the sealing member from the displacement rod for reducing the static friction on the displacement rod when the displacement rod move from a stagnant position within the pressured system.

    Abstract: The suspension strut of an embodiment of the invention includes a compressible fluid, a sleeve structure, a hydraulic tube adapted to contain a portion of the compressible fluid, a displacement rod and cavity piston coupled to the sleeve and adapted to move into the hydraulic tube upon the compression movement of the wheel and to move out of the hydraulic tube upon the rebound movement of the wheel, and a hydraulic seal located between the hydraulic tube and the displacement rod. The hydraulic tube defines a hydraulic cavity adapted to contain a portion of the compressible fluid and to cooperate with the compressible fluid to supply a suspending spring force that biases the wheel toward the surface.

    Abstract: A suspension system for a vehicle having left and right wheels is disclosed and claimed. The system includes first and second suspension struts and first and second hydraulic cavities to supply first and second suspending spring force for the left and right wheels, respectively. The system also includes a volume modulator to selectively push fluid into and vent fluid from the first and second hydraulic cavities, thereby actively modulating the first and second suspending spring forces. The volume modulator includes first and second modulator pistons and first and second cavity-side valves. In a preferred embodiment, the modulator pistons are cycled and the cavity-side valves are opened and closed to counteract roll of the vehicle. Further, in a preferred embodiment, the first modulator piston and the second modulator piston are located approximately 180null apart relative to an eccentric to minimize power consumption of the volume modulator during roll of the vehicle.
