The invention includes a pair of telescoping cylinders with oil flow from one chamber into the other being controlled to effect delay in the movement to absorb road shocks due to a change in the road.Field of SearchFront forks and headsChecked Yielding Independent wheel mounting Using diverse fluids Forming flexible wall enclosure for fluid Resistance alters relative to direction of thrust member (e.g., high resistance in one direction, low in the other) Thrust member or piston structure Piston valve detail (e.g., seat design, structural arrangement, metering element) Via fixed or variable orifice in piston Fluid through or around piston within chamber With retarder | |
