Abstract: A pressure relief valve (10) in a hydraulic tensioner for an endless loop power transmission member and method of assembly can include a check valve member (18) positioned within a fluid passage (14) defined by a housing (12) for movement toward and away from a valve seat (16) defined by the housing (12), a spring (20) normally biasing the check valve member (18) toward the valve seat (16), and a spring retainer (22) assembled within the fluid passage (14) to a variable depth in response to feedback pressure for automatically adjusting a biasing force of the assembled spring (20) to compensate for tolerances effecting a relief pressure value of an assembled pressure relief valve and allowing control of the relief pressure value to be within a predetermined range with respect to a predetermined target relief pressure value for driving the check valve member (18) away from the valve seat (16).

Abstract: A number of variations may include a sprocket using one or more slot(s) and/or compressive or elastic material in order to lower the NVH. A number of variations may include a sprocket which isolates the vibrations created by the impact of the chain with the sprocket so that the vibrations are prevented from traveling into the shaft.

Abstract: A check valve (30, 130, 230, 330, 430) can include a housing (132, 232, 332, 432) defining a plurality of inlet passages (138, 238, 338, 438) with a corresponding plurality of valve seats (148, 248, 348, 448) and an outlet passage 5 (140, 240, 340, 440) in fluid communication with the inlet passages (138, 238, 338, 438) through a cavity (142, 242, 342, 442). At least one valve disk (144, 244, 344, 444) has at least one valve sealing surface (146, 246, 346, 446) engageable with a corresponding one of the valve seats (148, 248, 348, 448). At least one biasing member (150, 250, 350, 450) normally biases the at least one valve disk (144, 244, 10 344, 444) toward a seated sealed position while allowing reciprocal movement within the cavity (142, 242, 342, 442) to an unseated position spaced from the valve seat (148, 248, 348, 448) allowing fluid flow therethrough.

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 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.

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.
