  • Patent number: 9982760
    Abstract: A tensioner includes a base, a tension arrangement rotatable at the base, a damping member being rotated in a loading direction by the tension arrangement, and an elastic member biasing against the damping member. The position of the damping member depends by the layout geometry of the specific application and is directly in opposition to the hub load. The reaction force of the cylindrical surface of the base on the damping member is very near to the plan of the external forces represented by the hub load to minimize the deflection of the shaft. The tension arrangement is rotated to push the damping member for generating a first positive tension between the damping member and the base, and to expand the elastic member radially for generating a second positive tension between the elastic member and the damping member, so as to enhance a damping force of the tensioner.

  • Patent number: 9982775
    Abstract: Ground wires are shared between a drive-side pulley solenoid valve and a driven-side pulley solenoid valve. Therefore, when a disconnection or short circuit occurs in the shared portion, a drive-side pulley and a driven-side pulley show substantially the same behavior. As a result, changes in the speed ratio ?cvt of a continuously variable transmission are suppressed and changes in vehicle behavior are also suppressed. Therefore, it is possible to suppress the degradation of drivability during the failure of the solenoid valves involved in power transmission.

  • Patent number: 9982779
    Abstract: A hydraulic control system provides lubrication fluid to a gearbox via two flow paths in parallel. One of the flow paths includes a passive thermal valve in series with a heat exchanger. When the fluid temperature is elevated, the thermal valve opens such that fluid flows through the heat exchanger for cooling. The thermal valve restricts flow to the heat exchanger when transmission fluid is in a normal operating temperature range, reducing flow demands. When the flow demands are reduced, a variable displacement pump requires less torque improving fuel economy. The thermal valve may also open when the fluid is below the normal operating temperature such that the heat exchanger heats the fluid. The parallel path may include a regulator valve. When the pressure of fluid in the lubrication circuit is elevated, the regulator valve reduces flow through the parallel path and may also divert flow to a sump.

  • Patent number: 9982789
    Abstract: A system, in certain embodiments, includes an annular ball valve seat including an annular spring, which biases the annular ball valve seat axially. More specifically, in certain embodiments, the annular ball valve seat includes a main body section, a lip section extending from the main body section, and a seat groove between the main body section and the lip section, wherein the first annular spring is disposed within the seat groove. A first leg of the annular spring biases the lip section in a first axial direction and a second leg of the annular spring biases the main body section in a second axial direction opposite the first axial direction. The annular ball valve seat is configured to be disposed within a ball valve, on either side of a ball of the ball valve. The particular design of the annular ball valve seat enables pressure within a body cavity of the ball valve to be self-relieving.

  • Patent number: 9982790
    Abstract: Examples are provided that describe a rotary hydraulic valve. In one example, a rotary valve comprises a sleeve with a plurality of selector ports and one or more control ports spaced along a length of the sleeve. A spool comprising an internal chamber is provided within the sleeve. The spool includes a plurality of selector openings and one or more control openings spaced along a length of the spool. The rotary valve also comprises a controller for determining a given rotational movement of the spool based on a selection of a pressurized fluid. The rotary valve also comprises a motor coupled to the spool and for rotating the spool within the sleeve based on the given rotational movement. The motor is configured to cause a given alignment of the spool to the sleeve resulting in a pathway through the internal chamber of the spool and out to the sleeve.

  • Patent number: 9982791
    Abstract: Valve devices for selectively controlling fluid flow through multiple converging paths are described. An example valve device comprises a housing defining first and second inlet paths, an outlet path, a junction in fluid communication with the first and second inlet paths and the outlet path, and first and second plunger cavities. A first movable plunger is disposed in the first plunger cavity and a second movable plunger is disposed in the second plunger cavity. A control member is slidably attached to the housing and is movable between a first, proximal position with the first plunger in a first position to impede fluid flow through the first inlet path and the second plunger is in a second position, and a second, distal position with the first plunger in a second position and the second plunger in a first position to impede fluid flow through the second inlet path.

  • Patent number: 9982793
    Abstract: A snap-action valve assembly includes a valve flap positioned within a conduit for controlling exhaust flow through the conduit. A shaft supports the valve flap in the conduit for rotation about a pivot axis between a closed position and an open position. A guide is fixed to the valve flap. A torsion spring is positioned at least partially outside the conduit and includes a first end restricted from rotation in at least one direction. The torsion spring includes a second end coupled to the guide. The torsion spring is preloaded to urge the valve flap into contact with an inner surface of the conduit when the valve flap is in the closed position.

  • Patent number: 9982797
    Abstract: A solenoid valve has a valve body with first and second passages; a coil wound around a coil bobbin; a stator with a third passage; a plunger having a through hole therein; a flux return device; and a spring. When the coil is energized, the plunger is attracted toward the stator such that the plunger closes the third passage, and connects the first passage with the second passage through the through hole in the coil bobbin. When the coil is not energized, the plunger moves away from the stator such that the plunger closes the first passage, and connects the second passage with the third passage. A resilient gasket between the stator and the flux return device reduces vibration from direct contact between the plunger and the stator, being transmitted to the flux return device, thereby reducing vibration and noise.
