Abstract:
1. A shock absorber comprising: a pressure tube defining a fluid chamber; a piston disposed within said fluid chamber, said piston dividing said fluid chamber into an upper working chamber and a lower working chamber; a compression passage extending through said piston between said upper and said lower working chambers; a compression valve assembly engaging said piston, said compression valve assembly closing said compression passage; a rebound passage extending through said piston between said upper and said lower working chambers; a rebound valve assembly engaging said piston, said rebound valve assembly closing said rebound passage; a bleed passage extending through said piston between said upper and said lower working chambers; a first bleed valve assembly engaging said piston, said first bleed valve assembly and said bleed passage defining a first flow path between said upper and lower working chambers extending through said piston and a second flow path between said upper and lower working chambers extending through said piston, said second flow path being different from said first flow path; wherein said first bleed valve assembly includes a first closing disc and a first orifice disc, said first closing disc movable between a first position where said first closing disc is spaced from said first orifice disc to open said second flow path and a second position where a said first closing disc is in direct engagement with said first orifice disc to close said second flow path.
