Abstract
A hydraulic tensioner for a drive system, including a flexible, inextensible drive element, has a bi-directional travel limiter associated with a hydraulically biased tensioning cylinder. The travel limiter is bi-directional because it limits not only loading of the tensioning cylinder against a tensioner shoe in a direction tending to tighten a drive element, but also resists movement of the tensioner shoe in a direction tending to allow slack in a drive element.
