Abstract:
A hydraulic damper including a high frequency valve assembly for reducing the level of damping force provided by the hydraulic damper during a rebound stroke during high frequency and/or low amplitude events.

Claim (Index 1):
A hydraulic damper assembly including:\n a tube extending about and along an axis and defining a chamber; a main piston slideably disposed in said tube and dividing said tube into a compression section and a rebound section and moveable in a compression stroke toward said compression section and a rebound stroke toward said rebound section; said main piston having an upper end facing said rebound section of said chamber and a lower end facing said compression section of said chamber; a rod connected to and extending through said main piston in said compression and rebound sections; said main piston defining a compression passage extending between said upper and lower ends of said main piston and fluidly connecting said compression and rebound sections; a compression valve overlying said compression passage at said upper end of said main piston for allowing fluid to pass from said compression section to said rebound section during a compression stroke of said main piston while preventing fluid from passing from said rebound section to said compression section through said compression passage; said piston further defining a rebound passage extending between said lower and upper ends of said main piston and fluidly connecting said compression and rebound sections; a rebound valve overlying said rebound passage at said lower end of said main piston for allowing fluid to pass from said rebound section to said compression section during a rebound stroke of said main piston while preventing fluid from passing from said compression section to said rebound section through said rebound passage; a supplemental housing disposed about said rod in said compression section and disposed axially against said rebound valve and defining a compartment and axially moveable relative to said rod; a spring biasing said supplemental housing toward said rebound valve; a high frequency piston fixed relative to said rod inside said supplemental housing and separating said compartment into a bottom segment and a top segment and defining at least one high frequency passage fluidly connecting said top segment and said bottom segment; and a high frequency valve overlying said high frequency passage on a bottom face of said high frequency piston and allowing fluid to pass through said high frequency passage from said top segment to said bottom segment while substantially inhibiting fluid from passing from said bottom segment to said top segment to axially move said housing away from said rebound valve to provide a reduction of damping force during high frequency vibrations or low amplitude events.
