Patent ID: 7690666

Claim:
A suspension damper, comprising: a piston rod carrying a piston; a tube defining a piston chamber, said piston configured for reciprocal movement within said piston chamber; a reservoir chamber defined by said damper; a divider that separates a gas chamber of said damper from said reservoir chamber, said divider configured to move to vary a volume of said reservoir chamber to accommodate fluid displaced from said piston chamber by said piston rod; and a flow passage connecting said piston chamber and said reservoir chamber; a first valve having a first position and a second position, wherein said first valve permits a first rate of fluid flow through said flow passage in said first position and wherein said first valve permits a second rate of fluid flow through said flow passage in said second position; and an inertia valve including an inertia mass, said inertia mass movable between an open position and a closed position, wherein, in said closed position, fluid flow through said inertia valve is substantially prevented and, wherein in said open position, fluid flow through said inertia valve is permitted; wherein movement of said divider moves said first valve between said first position and said second position.
