    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.

    Abstract: A press-fit check valve for a hydraulic tensioner includes a retainer, a seat, a ball, and a spring. The seat of the check valve is press-fit against the wall of the check valve counterbore of the hydraulic tensioner body. In some embodiments, the seat is cup-shaped to provide a predetermined level of press force retention of the press-fit check valve. In some embodiments, the seat includes a plurality of legs separated by leg openings. In some embodiments, a backflow path is provided past the press-fit check valve by a combination of the leg openings and at least one backflow slot through a flange of the retainer. In some embodiments, a lip at the outer end of the check valve counterbore prevents the seat from backing out of the check valve counterbore.

    Abstract: A check valve assembly (20) and method of assembly can include a hydraulic tensioner (10) having a body (12) defining an inlet fluid passage with an inlet fluid passage port (14a) having a valve seat (14b). The check valve assembly (20) can include a retainer (22) located within the body (12), a valve disk (30) having a sealing surface (32), and a biasing member (34) normally biasing the valve disk (30) toward the inlet fluid passage port (14a). The retainer (22) can define an outlet passage (24). The valve disk (30) and the biasing member (34) can be received within a cavity (26) of the retainer (22). The biasing member (34) can allow reciprocal movement of the valve disk (30) from a closed seated position sealing the inlet fluid passage port (14a) to an open unseated position spaced from the inlet fluid passage port (14a) opening the inlet passage.

    Abstract: A product for applying tension is disclosed. The product may include a block with a first bore opening into to the block. A body may be provided having a second bore substantially larger in diameter than the first bore. The body may be positioned against the block so that the first bore is open to the second bore. The body may have a passage for providing fluid to a pressure chamber from the second bore. The passage may be arranged to open to the second bore and form a tangent to the second bore. Fluid may flow from the first bore to the pressure chamber through the second bore and the passage substantially unimpeded. Fluid flow is impeded from the passage to the first bore as a result of the configuration of the first bore, second bore and passage.
