Abstract

A belt tensioner for use in an engine comprises a fixed structure attached to the engine and a moveable structure biased in a belt tensioning direction. One of the fixed and movable structures defines a fluid chamber containing an incompressible fluid, while the other of the two structures defines a chamber dividing structure within said fluid chamber. The fluid dividing structure defines two chamber portions and is constructed such that relative movement of the moveable structure displaces fluid from one chamber portion to the other. The chamber dividing structure is also configured so as to allow the fluid to flow between chamber portions in a restricted manner so as to yieldingly resist the relative movement of the moveable structure, whereby the fluid flow restriction is greater when the moveable structure moves in the opposite direction than when the moveable structure moves in the belt tensioning direction.
