ABSTRACT:
A chain tensioner system having a dual arm blade and a hydraulic tensioner. A hydraulic tensioner applies force against the free ends of the dual arms. Each arm is supported in two places, i.e., at the pivot point and against the tensioner piston. A face material that has a high P/V rating is added to the surface of the arm. The arms are simple flat plastic shoes with a hole at one end for the pivot point. A blade spring can be inserted into one or both of the plastic shoes. The tensioner piston moves in and out, the arms in the dual arm tensioner system slide against one another. As one of the tensioner arms applies the force to the chain the other arm damps the movement of the first arm.
