  • Bicycle shock assemblies with plunger operated valve arrangement
    Patent number: 9815517
    Abstract: A shock absorber, which is particularly applicable to bicycles, includes a secondary chamber whose volume selectively contributes to a volume associated with a primary chamber of the shock. A piston is supported by a compression rod and cooperates with a shock tube to define the primary chamber. The secondary chamber is fluidly isolated from the primary chamber by a valve arrangement positioned proximate the piston. A plunger extends along a longitudinal length of the shock and forms or interacts with the valve arrangement such that the secondary chamber is selectively fluidly connected to the primary chamber so the primary and secondary chambers of the shock assembly contribute to the performance of the shock for a selected portion of shock travel.
