摘要： 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.

摘要： A tensioner including a housing having a bore, a hollow piston, a piston spring, a check valve between the source of pressurized fluid and hollow piston, and a pawl plate. The hollow piston is slidably received within the bore of the housing and forms a fluid chamber with the bore. The hollow piston also has a plurality of grooves formed along the outside thereof. The piston spring biases the piston in an outward direction from the bore. The pawl plate has a bottom with a protruding pawl ridge that meshes with the grooves on the piston. The pawl plate is received by the housing and receives a portion of the piston. One side of the pawl plate is biased in the outward direction by a vertical spring or springs and in a lateral direction by a horizontal spring.
