Claim Text:
1. A shock absorber comprising: a pressure tube forming a working chamber; a piston body slidably disposed within said working chamber, said piston body dividing said working chamber into an upper working chamber and a lower working chamber; means for defining a fluid chamber in communication with one of said upper working chamber and said lower working chamber; a compression valve assembly controlling fluid flow from said lower working chamber to said fluid chamber; a pressure sensitive valve assembly separate from said compression valve assembly disposed between said lower working chamber and said fluid chamber, said pressure sensitive valve assembly movable from an open position allowing fluid flow to said compression valve assembly from said lower working chamber to a closed position restricting but not eliminating said fluid flow to said compression valve assembly from said lower working chamber based upon a velocity of said piston body sliding in said pressure tube; and a secondary valve assembly separate from said pressure sensitive valve assembly and said compression valve assembly prohibiting all of said fluid flow to said compression valve assembly from said lower working chamber when said pressure sensitive valve assembly is in said closed position and when said secondary valve assembly is in a closed position.
