Abstract: A gas-filled spring (1) operates using gas (13, 14) and may be intended for a motor cycle. The gas-filled spring comprises a cylinder (2) and a piston (4), said cylinder comprising a compression chamber and a return chamber (8, 9). An arrangement maintains the necessary quantities of gas and gas pressure settings or differential pressures in the chambers despite any gas leakage and temperature variations occurring. Arranged between the chambers is a passage (12), which is open only in a predetermined position of the cylinder and the piston relative to one another. In the open position gas transfer between the chambers and/or pressure equalization in or differential pressure adjustment of the gas pressures in the chambers are permitted. The invention also relates to a valve for counteracting rapid changes in leakage and temperature. The desired spring characteristic of the gas-filled spring can in this way be maintained despite leakage and temperature variations.

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 passes intermediate the passage, the damper cavity, and the chamber of the outer piston.
