Abstract
A product for applying tension is disclosed. A block may have a first passage opening into the block. A body may have a first manifold and may be positioned against the block so that the first passage is open to the first manifold. The body may have a flow path for providing fluid from the first manifold to a second manifold and there through to a pressure chamber. The flow path may include a series of channels and may be configured to allow substantially unimpeded flow from the first manifold to the second manifold, and to impede flow from the second manifold to the first manifold. The flow path may be free of movable components.

A product for applying tension comprising:
- a block with a first passage opening into the block;
- a body having a first manifold, the body positioned against the block so that the first passage is open to the first manifold;
- the body having a flow path for providing fluid from the first manifold to a second manifold and through the second manifold to a pressure chamber;
- wherein the flow path includes a series of channels and is configured to allow substantially unimpeded flow from the first manifold to the second manifold;
- and wherein the flow path is configured to impede flow from the second manifold to the first manifold;
- and wherein the flow path is free of movable components.
A hydraulic tensioner for applying force to a component of an engine comprising:
- a body having a piston bore, a first manifold, and a second manifold;
- a piston slidably disposed in the piston bore defining a first chamber in the piston bore between the body and the piston;
- a first passage in the body extending between the piston bore and the second manifold;
- a second passage in the engine that is in fluid communication with the first manifold;
- a plurality of flow channels between the first manifold and the second manifold;
- wherein the flow channels are configured to allow substantially unimpeded flow from the first manifold to the second manifold and the flow channels are configured to impede flow from the second manifold to the first manifold and wherein the flow channels are free of movable components.
