Claim 0:
1. An active shock absorber system of a vehicle, comprising:
a housing that includes a compression volume and an extension volume;
a piston disposed in the housing that, in a first operating condition, is configured to move through at least a portion of a compression stroke and that, in a second operating condition, is configured to move through at least a portion of an extension stroke;
a hydraulic device which is configured to operate as—a hydraulic pump in a first mode of operation to apply an active force on the piston, wherein the hydraulic device includes a first port and a second port;
a controller configured to control the active shock absorber system to alter the force/velocity response of the active shock absorber system as a function of driving conditions;
a pressurized reservoir;
a hydraulic controls, with a multiplicity of valves configured and located to control flow to and from the pressurized reservoir, wherein the multiplicity of valves includes a first valve and a second valve, and wherein a hydraulic fluid exchange with the pressurized reservoir in the first mode of operation is controlled at least by the second valve in the hydraulic controls;
a first hydraulic flow path that fluidly connects the compression volume and the extension volume and passes through the first port and the second port of the hydraulic device; and
a second hydraulic flow path that fluidly connects the compression volume and the extension volume and passes through the first valve and the second valve of the hydraulic controls, wherein the second hydraulic flow path bypasses the hydraulic device.
