  • Patent number: 10208838
    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.

  • Patent number: 10208833
    Abstract: [Problem] To provide a chain link which can improve wear resistance even under lubricating conditions in adhesive mode. [Solution] Steel link plates 2 for a silent chain having pinholes 22 for inserting linking pins 3 are formed. A hardened layer obtained by performing heat treatment (martempering, for example) is formed on the inner circumferential surface of the pinholes 22, and a large number of hard particles hp having the same hardness as or a greater hardness than the surface hardness of said hardened layer are dotted in a crystalline state within the martensite structure on the surface layer section of the hardened layer. The hard particles hp are an oxide, carbide or nitride of any element from Cr, V, Ti and Nb which was originally present in the steel of the link plate material.

  • Patent number: 10183577
    Abstract: A transfer case includes primary and secondary output shafts, along with a secondary torque transfer mechanism and a locking mechanism, which are configured to selectively couple the primary and secondary output shafts. The secondary torque transfer mechanism comprises a sprocket coupled to the secondary output shaft, and a plate clutch coupled to the sprocket to selectively form a friction coupling with the primary output shaft. The locking mechanism selectively couples the primary output shaft to the sprocket, and includes a locking sleeve and an actuator that moves the locking sleeve between a first position and a second position. In the first position, the locking sleeve forms a first splined connection with the primary output shaft and forms a second splined connection with the sprocket. In the second position, the locking sleeve forms the first splined connection with the primary output shaft and forms a second splined connection with the sprocket.

  • Publication number: 20190017433
    Abstract: A linkage extends between an actuator and a valve in a turbocharger. The linkage comprises two spaced member bodies having central portions with opposing curved shapes that extend between ends translatable along and rotatable about spaced pivots. Translation of one member toward the other member compresses the central portions, increasing overall stiffness of the linkage, and translation of one member away from the other member creates a gap between the central portions, allowing independent translation of the ends along the spaced pivots to compensate for misalignment between the actuator and the valve caused by heat and vibration. Another linkage extending between an actuator and a valve in a turbocharger includes two planar spaced member bodies extending between ends translatable along and rotatable about spaced pivots. The two member bodies have different thicknesses.
