Abstract: A hydraulic tensioner (100) is designed for low cost and ease of manufacturing. A housing (102) has a bore (104) and a sleeve member (105) received within the bore. A piston (130) is slidably received within the sleeve member, forming a high pressure fluid chamber (180) with the sleeve member. The housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and sleeve member are constructed of drawn metal. The housing may be formed by injection molding. The sleeve member and other components of the tensioner may be assembled within the tensioner by inserting them into the mold during the injection molding process.
