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 19):
A stroke dependent damper assembly for attachment to a piston rod of a vehicle shock absorber having first and second working chambers, the stoke dependent damper assembly comprising:\n a damper housing having a proximal end configured to be coupled to the piston rod and a distal end opposite the proximal end; an end cap coupled to the damper housing, the end cap having an end wall with a through-bore, the end cap and the damper housing cooperating to define an internal cavity; a floating piston slidably received in the internal cavity for movement along a longitudinal axis between a retracted position, an intermediate position, and an extended position, the floating piston being unbiased and free floating in the internal cavity; and a metering pin extending longitudinally from the floating piston along the longitudinal axis to a metering pin end, the metering pin received in the through-bore to define an orifice between an inner surface of the through-bore and an outer surface of the metering pin that changes in size when the floating piston moves between the retracted, middle, and extended positions, the metering pin end projecting longitudinally outwardly from the end wall when the floating piston is in the retracted, middle, and extended positions, wherein the metering pin has an hour-glass shape and a cross-sectional width that narrows at a waist portion of the metering pin such that the metering pin progressively reduces an opening area of the orifice when the floating piston moves away from the intermediate position.
