Secondary dampening assembly for shock absorber

A shock absorber assembly comprising:

• a pressure tube having an upper end and a lower end and having a first diameter defining an interior;
• a rod guide disposed adjacent said upper end of said pressure tube;
• a first compression valve assembly adjacent said lower end of said pressure tube;
• a rod operatively coupled to said pressure tube having a first end supported by said rod guide for concentrically aligning said rod with said pressure tube and a second end opposite said first end with said second end disposed within said interior;
• a piston assembly coupled to said rod between said rod guide and said first compression valve assembly with said piston assembly disposed within said interior and slideably coupled to said pressure tube, and with said piston assembly dividing said interior into an upper working chamber and a lower working chamber;
• an extender coupled to said second end of said rod and a second compression valve assembly coupled to said extender between said piston assembly and said first compression valve assembly;
• a cup disposed within said lower working chamber of said pressure tube at said lower end with said cup having a second diameter less than said first diameter and with said cup defining a bore shaped to receive said second compression valve assembly;
• wherein said cup and said pressure tube define an intermediate chamber therebetween with said cup having a plurality of ribs defining a portion of said intermediate chamber into a plurality of slots for allowing fluid to flow therein during a compression stroke and a rebound stroke of said rod, and
• wherein said ribs include one or more crush ribs and said cup is engaged with said pressure tube via a press fit.

• a second compression valve assembly coupled to said extender between said piston assembly and said first compression valve assembly, and wherein said extender defines an indent with said second compression valve assembly disposed within said indent;
• a cup disposed within said lower working chamber of said pressure tube at said lower end with said cup having a second diameter less than said first diameter, and with said cup defining a bore shaped to receive said second compression valve assembly;
• wherein said pressure tube includes an upper section having a first diameter and a lower section having a third diameter greater than said first diameter and said cup is disposed within said lower section;
• and
• a sleeve disposed between said extender and said second compression valve assembly with said sleeve and said extender defining a gap therebetween for allowing movement of said second compression valve assembly in a direction transverse to movement of said extender.
