Hydraulic damper assembly including an anti-noise member

A hydraulic damper assembly comprising:

• a main tube disposed on a center axis extending between a first end and a second end defining a fluid chamber extending along said center axis for containing a working fluid;
• an external tube disposed spaced apart from said main tube and extending about said main tube between a closed end and an opened end with said closed end being adjacent to said first end and said opened end being adjacent said second end defining a compensation chamber between said main tube and said external tube;
• a cap attaching to said closed end to close said fluid chamber and said compensation chamber;
• a main piston slidably disposed in said fluid chamber and movable along said center axis dividing said fluid chamber into a compression chamber between said first end and said main piston and a rebound chamber between said second end and said main piston;
• a piston rod extending along said center axis attached to said main piston for moving said main piston between a compression stroke and a rebound stroke;
• an additional piston coupled to said piston rod and axially spaced from said main piston, located in said fluid chamber, to provide an additional damping force during said compression stroke and said rebound stroke;
• said additional piston having a top surface and a bottom surface and defining at least one pathway extending through said additional piston;
• said additional piston defining a recess bounded by an upper surface and a lower surface, the recess being located between said top surface and said bottom surface and extending about said additional piston;
• a ring slidably disposed in said recess;
• and
• said additional piston including an anti-noise member located in said recess whereby said anti-noise member releases fluid pressure between said ring and said upper surface of said recess thereby reducing noise generation during said compressions stroke and said rebound stroke.
