    Abstract: A shock absorber including: a first cylinder having an interior, first and second ends and defining an axis, wherein the interior includes a damping fluid chamber and a damping piston movably mounted therein for movement between the first and second ends, wherein the damping piston is mounted on a first end of a shaft, wherein the first end of the shaft is movably retained within the interior of the first cylinder; first and second bypass openings configured for opening into the damping fluid chamber at first and second axially spaced-apart positions; a bypass channel fluidly coupling the first and second bypass openings; a fluid metering valve; and a floating piston dividing a portion of the shock absorber into a gas chamber and the reservoir chamber, wherein the fluid metering valve and the floating piston define the reservoir chamber there between.

    Abstract: An apparatus and system are disclosed that provide position sensitive suspension damping. A damping unit includes a piston mounted in a fluid-filled cylinder. A vented path in the piston may be fluidly coupled to a bore formed in one end of the piston rod, creating a flow path for fluid to flow from a first side of the piston to a second side of the piston during a compression stroke. The flow path may be blocked by a needle configured to engage the bore as the damping unit is substantially fully compressed, thereby causing the damping rate of the damping unit to increase. In one embodiment, the piston includes multiple bypass flow paths operable during the compression stroke or the rebound stroke of the damping unit. One or more of the bypass flow paths may be restricted by one or more shims mounted on the piston.
