Claim 13:
14. An active shock absorber system of a vehicle, comprising:
a housing that includes a first volume and a second volume;
a piston slidably disposed in the housing that in a first mode is configured to move through at least a portion of a compression stroke and that in a second mode is configured to move through at least a portion of an extension stroke;
a hydraulic device, wherein the hydraulic device is configured to operate as a hydraulic pump in at least one mode of operation to apply an active force on the piston, wherein the hydraulic device includes a shaft, a first port and a second port, wherein the first port is in fluid communication with the first volume and the second port is in fluid communication with the second volume;
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 first hydraulic flow path that fluidly connects the first port and the pressurized reservoir, wherein a hydraulic flow in the first flow path is, at least partially, controlled by a first valve;
a second hydraulic flow path that fluidly connects the second port and the pressurized reservoir, wherein a hydraulic flow in the second flow path is, at least partially, controlled by a second valve; and
a third hydraulic flow path that fluidly connects the first volume and the second volume and passes through the hydraulic device and the first port and the second port, wherein the third hydraulic flow path bypasses the first valve and the second valve.
