Patent ID: 8517153

Claim:
A valve for a suspension damping system, the valve comprising: a valve body separating a first fluid chamber from a second fluid chamber, the valve body having at least one fluid port therethrough between the first and second fluid chambers; a shim valve assembly coupled to the valve body and configured to control fluid flow across the valve body, the shim valve assembly including: a first shim having at least one fluid port, and a second shim, wherein the second shim includes at least one tab configured to seal the first shim fluid port, the first and second shims configured to flex in a first direction under fluid pressure to permit fluid flow between the first and second fluid chambers, providing a first resistance to fluid flow, the at least one tab of the second shim sealing fluid flow through the first shim fluid port during flow in the first direction, only the second shim configured to flex in a second direction under fluid pressure to permit fluid flow between the first and second fluid chambers, providing a second resistance to fluid flow, the at least one tab of the second shim permitting fluid flow through the first shim fluid port during flow in the second direction; and a fluid passageway formed through the first and second shims and valve body to permit fluid flow in both first and second directions between the first and second fluid chambers without displacing the first or second shims.
