Abstract:
A damper system for a vehicle including a pressure tube and a piston assembly. A stroke dependent damper assembly is coupled to a piston rod at a position below the piston assembly. A free floating piston positioned in an internal cavity of the stroke dependent damper assembly is longitudinally moveable between retracted, middle, and extended positions. A metering pin extends from the floating piston into a through-bore in a distal end of the stroke dependent damper assembly. An orifice is defined between an inner surface of the through-bore and an outer surface of the metering pin. Longitudinal movement of the floating piston changes the position of the metering pin in the through-bore, which changes the size of the orifice. Fluid flow through the orifice is restricted when the orifice size decreases, which slows down the movement of the floating piston as it approaches the retracted and extended positions.

Claim (Index 11):
A damper system for a vehicle, comprising:\n a pressure tube; a first piston assembly slidably fitted in the pressure tube for movement along a longitudinal axis, the first piston assembly separating the pressure tube into a first working chamber and a second working chamber, the first piston assembly including a first valve assembly that controls fluid flow between the first working chamber and the second working chamber; and a stroke dependent damper assembly including a proximal end coupled to the first piston assembly, a distal end opposite the proximal end, an internal cavity between the proximal and distal ends, and a floating piston slidably received in the internal cavity for movement between a retracted position, an intermediate position, and an extended position, the distal end having an end wall with a through-bore, the floating piston contacting a first stop when at the retracted position and contacting a second stop that is spaced apart from the first stop when at the extended position, the floating piston and the through-bore defining an orifice that changes in size when the floating piston moves between the retracted and extended positions to reduce the velocity of the floating piston as the floating piston approaches the retracted and extended positions.
