Abstract
A vehicular fluid damper system comprises a piston-type actuator, a static fluid damper, first and second flow passages, a first flow control valve, and a controller. The piston-type actuator comprises a cylinder and a piston that cooperate with one another to define first and second chambers. The static fluid damper defines first, second, and third dampening chambers. The first and second dampening chambers are in fluid communication with one another. The second and third dampening chambers are in fluid communication with each other. The first flow passage is in fluid communication with the first dampening chamber and the first chamber. The second flow passage is in fluid communication with the second dampening chamber and the second chamber. The controller is configured to facilitate operation of the first flow control valve to change a flow rate of fluid through the first flow passage.
