  • Chain drive of a V-engine having overhead camshafts
    Patent number: 6431133
    Abstract: A chain drive of a V-engine with overhead camshafts includes chains which are driven by a crankshaft. In each case the overhead cam shafts are driven by a separate chain. Tensioner blades swivellably assigned to a respective slack run of the chains are acted upon by hydraulic chain tensioners of the same type of construction. The chain tensioners are arranged in an accessible manner on the exterior side on the V-engine and interact with sloped contact ramps on the tensioner blades. The chain tensioners of the same construction are arranged transversely to one another on the V-engine and are configured for a reliable venting in each installed position by including two mutually independently operating leakage devices.
