Abstract

A steering damper system and method of regulating the fluid pressure of such a system are provided. The system can comprise a piston rod, a cylinder, a passage, and a damper portion. The damper portion can comprise a damper cavity, an outer piston, an inner piston, and a biasing component. The damper cavity can be in fluid communication with the passage. The outer piston can be slidably disposed in the damper cavity and define a chamber and a duct that is in fluid communication with the chamber and the passage. The inner piston can be slidably disposed in the chamber of the outer piston. The biasing component can exert an axial biasing force against the inner piston for regulating the pressure of fluid disposed in the system passing intermediate the passage, the damper cavity, and the chamber of the outer piston.
