Abstract
A chain tensioner comprising an integrated tensioner body and tensioner arm. The tensioner body includes a fluid reservoir and a tensioner bore. The tensioner arm includes a pivot bore with a pivot pin disposed in the pivot bore to pivotally mount the tensioner arm. A check valve connecting the fluid reservoir to the tensioner bore permits fluid to flow into the tensioner bore, but not into the fluid reservoir. A plunger is slidably fitted into the tensioner bore and biased out from the tensioner bore by the fluid pressure in the tensioner bore. As a result, the plunger is forced against a fixed boss, causing rotational movement of the tensioner body and tensioner arm.
