Patent Images
1. A vehicle suspension component comprising:
- a shock absorber movable between rebound and compression positions; and
an external valve in fluid communication with said shock absorber to control stiffness of said shock absorber, said external valve including a valve housing, a piston received within said valve housing, a blow-off ring movable relative to said piston between an initial position and a blow-off position, and at least one deflection disc have a preload to bias the blow-off ring toward said initial position wherein said blow-off ring is movable to said blow-off position when fluid pressure exceeds said preload.

Abstract
A vehicle suspension component includes a shock absorber movable between rebound and compression positions and an external valve in fluid communication with the shock absorber to control shock absorber stiffness. The external valve has a valve housing, a piston received within the valve housing, and a blow-off ring movable relative to the piston between an initial position and a blow-off position. At least one deflection disc has a preload to bias the blow-off ring toward the initial position and the blow-off ring is movable to the blow-off position when fluid pressure exceeds the preload.

10. An adaptive damping valve for a suspension component comprising:
-
a valve housing including at least first and second chambers; a pilot portion received within said first chamber; and a main stage received within said second chamber, said main stage including a piston, a blow-off ring movable relative to said piston between an initial position and a blow-off position, and at least one deflection disc that has a preload to bias said blow-off ring toward said initial position. - View Dependent Claims (11, 12, 13, 14, 15, 16)
