Abstract
A tensioner is disclosed that may be part of a power system where the tensioner provides tension to an endless power transmitting element such as a belt, chain, or other continuous loop. The tensioner has an arm that is rotatable about a first axis. The tensioner also includes an outer spring and at least one inner spring. The outer spring has an outer coil that defines an outer diameter. The inner spring has an inner coil that defines an inner diameter. The inner diameter of the inner coil is less than the outer diameter of the outer coil such that at least a portion of the inner spring is received by the outer spring. The outer spring and the inner spring both urge the arm to rotate about the first axis and into tensioning engagement with the power transmitting element.
