Abstract
An accessory drive system for an automotive engine includes a drive pulley attached to an output shaft of the engine and a flexible drivebelt for connecting the drive pulley with driven pulleys. A tensioner maintains the drivebelt in contact with each of the drive and driven pulleys. The tensioner includes an arm which is rotatably mounted to the engine which has a wheel for contacting the drivebelt. The wheel is urged into contact with the drivebelt by the arm, with the tensioner further including a governor for controlling rotational motion of the arm with the arm being able to rotate freely in the direction in which tension of the drivebelt is increased, with the governor resisting motion of the arm in the direction in which tension in the drivebelt is decreased.
