Abstract: A multi-path fluid flow control valve for a shock absorber that restricts fluid into a first path while opening fluid flow to a second path when a given fluid flow velocity is reached. Exemplary configurations of this diverter valve are disclosed such as a spring loaded disc valve with face sealing lands, and a spool valve with diametric sealing lands. Applications include active suspension dampers in order to limit maximum RPM into a hydraulic motor. For such a system, in one mode the diverter valve allows fluid to move unrestricted into the hydraulic motor. When fluid velocity reaches a tunable set point, in a second mode the diverter valve restricts flow into the hydraulic motor and bypasses it shuttling fluid into the opposite side of the damper. In some cases progressive damping valves are utilized in series or parallel to smooth damping characteristics during, before, and after transitions.

Abstract: Various embodiments related to hydraulic actuators and active suspension systems as well as their methods of use are described. Hydraulic actuators have long been used for motion control including, for example, active suspension systems which apply energy to the active suspension in response to various loads applied to a wheel and/or associated vehicle body. In order to achieve a desired level of performance, an active suspension system needs to have energy either already present or capable of being provided at an appropriate time.
