Abstract: A tensioner for a closed loop power transmission system for an internal combustion engine having a drive shaft terminating in a sprocket and at least one camshaft, each terminating in a sprocket, with a single continuous chain wrapping around all of the sprockets. The tensioner contains a pair of elongated tensioning arms, each one in slidable contact with one of the two strands of chain that traverses between the driving sprocket and the driven sprocket(s). Each tensioning arm contains a wear face that remains in constant slidable contact with the strand of chain to which it is adjacent. An adjusting arm connects one of the ends of the tensioning arms. The adjusting arm has a ratchet means that adjusts for the backlash in the system and takes up any slack in the chain.

Abstract: A tensioner comprising a piston slidably received within a piston bore of the housing having a plurality of grooves formed on an outer circumference, the piston forming a first pressure chamber with the piston bore. The tensioner uses a mechanism to remove a sliding pawl or expandable clip from engaging the grooves on the piston, such that the piston can move towards the housing and reduce chain load when fluid pressure is reduced in the first pressure chamber during engine shutdown, but not so much as to leave the chain uncontrolled during engine restart. The mechanism may for example be a fluid biased spool piston which engages the expandable clip or a pawl piston that engages a sliding pawl.

Abstract: A cushion ring (102) is received in a concentric groove in a sprocket (112) with teeth and a hub. More specifically, the groove is defined between an annular portion of the hub and the teeth. The cushion ring has an inner ring (106) and an outer ring (104). The outer ring is made of an incompressible material that has a load bearing area for receiving load from the links of the chain. The load and engagement noise energy of the chain links are combined and distributed over a large area of the outer ring. The inner ring receives this distributed load and noise energy from the outer ring and absorbs most of such energy. This improved distribution decreases wear and increases life of the resilient material while also providing for a reduced level of chain engagement noise.
