ABSTRACT:
A hydraulic tensioner is designed for low cost and ease of manufacturing. A piston housing has a bore and a bore cup member received within the bore. A piston is slidably received within the bore cup member, forming a high pressure fluid chamber with the bore cup member. The piston housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and bore cup member are constructed of drawn metal. A single channel connects the pressure chamber to an external source of fluid, and a single valve system regulates the flow of fluid into the pressure chamber. The inexpensive materials and simple design provide for a low cost hydraulic tensioner.
