Method for arranging a separating piston in a cavity and a device with such a separating piston

A steering damper system comprising:

• a piston rod comprising an elongate shaft, a piston component and a mounting section, the piston component being fixed along the shaft of the piston rod and defining a diameter larger than a diameter of the shaft;
• and
• a damper module comprising:
• a cylinder defining top and bottom ends, the cylinder being configured with the piston rod being slidably disposed therein, the cylinder defining an inner surface having a diameter greater than the diameter of the piston component to form a seal with the piston component, the cylinder defining upper and lower sections, the upper section being that portion of the cylinder intermediate the piston component and the top end of the cylinder, the lower section being that portion of the cylinder intermediate the piston component and the bottom end of the cylinder;
• a passage being in fluid communication with the upper and lower sections of the cylinder, the passage defining a volume;
• a pressure regulation portion being in communication with the passage and being operative to modify the volume of the passage for regulating the pressure of a fluid disposed within the passage and the upper and lower sections of the cylinder;
• and
• a damper portion comprising a damper cavity, a separating piston component and a biasing component, the separating piston component being slidably disposed within the damper cavity to define first and second sections of the damper cavity, the second section of the damper cavity being in fluid communication with the passage, the separating piston component comprising outer and inner parts, the outer part being slidably disposed within the damper cavity and being configured to form a seal with an inner surface of the damper cavity, the outer part comprising an interior chamber and a duct, the duct being in fluid communication with the interior chamber of the outer part and the second section of the damper cavity, the inner part of the separating piston component being slidably disposed within the interior chamber of the outer part of the separating piston component and being configured to form a seal with an inner surface of the interior chamber, the biasing component being disposed in the first section of the damper portion and biasing the inner part of the separating piston component against at least a portion of the damper module.
