Abstract
A piston () comprises a first pair of passive flow-control valves () [namely, a first compensation valve () and a first rebound valve ()], a second pair of passive flow-control valves () [namely, a second compensation valve () and a second rebound valve ()], and a flow-dividing solenoid valve () shiftable between a first operating position [in which it allows flow of a damping fluid between an upper chamber and a lower chamber of a shock absorber through the first pair of passive flow-control valves () and second pair of passive flow-control valves ()] and a second operating position [in which it allows the flow of the damping fluid between the upper chamber and lower chamber through only the second pair of passive flow-control valves ()]. The solenoid valve () is normally open (i.e., it is normally kept in the first operating position).
