    摘要： PROBLEM TO BE SOLVED: To facilitate assembling an oil seal to a variable valve timing mechanism, and thereby to enhance workability and prevent the assembling of a spring from being forgotten.SOLUTION: The spring 20 is engaged and integrated with a seal member 10. Specifically, a locking part 22 is formed by bending the end of the spring 20, and the locking part 22 is press-inserted into an engagement groove 16 of the seal member 10, thus making the seal member 10 and the spring 20 engaged with each other.

    摘要： PROBLEM TO BE SOLVED: To provide a valve opening/closing time controller having a seal member that can be assembled for preventing a leak of a working fluid between an advanced angle chamber and a retarded angle chamber without processing a tapered portion that is formed when a drive rotor and a driven rotor are manufactured by die casting.SOLUTION: The valve opening/closing time controller includes: a drive rotor 1; a driven rotor 2; partitions 21 which are formed on at least either the drive rotor 1 or the driven rotor 2 to partition a space into the retarded angle chambers and the advanced angle chambers; seal members SE which prevent a leak of a working fluid between the retarded angle chambers and the advanced angle chambers due to a relative rotation between the drive rotor 1 and the driven rotor 2; and biasing members SP which biases the seal members SE. At least either the drive rotor 1 or the driven rotor 2 is manufactured by die casting. At least either the partition 21 or a surface facing the partition 21 of the rotor 1 or 2 manufactured by die casting is composed of an inclined surface 12A of a tapered portion.

    摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device capable of improving the internal leakage sealing property between a lead angle oil pressure chamber and a lag angle oil pressure chamber and improving endurance of a seal plate.
    SOLUTION: A seal plate 50 is held between a shoe housing 3 to be rotated synchronously with a driving shaft and a gear 1. An elastic part 55 of the seal plate 50 is provided in a range corresponding to a predetermined relatively movable angle range of a vane part 9(c) of a vane rotor rotatable by a predetermined phase difference with respect to the driving shaft. The elastic part 55 forms a pressure chamber 66 between the end face of the gear 1 for introducing a pressured oil in a lead angle oil pressure chamber 65 to the pressure chamber 66 via a pressured oil introduction path 53. Since the elastic part 55 is pressed toward a vane part 9(c) by the elastic force over a wide range and also by the pressure difference of the pressure chamber 66 and a lag angle oil pressure chamber 62, the internal leakage sealing property is improved. Furthermore, since the load by the elastic force is not concentrated locally, endurance of the seal plate 50 is improved.

    摘要翻译： 要解决的问题：提供一种能够提高引导角油压室和滞后油压力室之间的内部泄漏密封性的气门正时调整装置，提高密封板的耐久性。 解决方案：密封板50保持在与壳体3之间以与驱动轴和齿轮1同步旋转的状态。密封板50的弹性部分55设置在与预定的相对可移动角度 叶片转子的叶片部分9（c）的范围可相对于驱动轴旋转预定的相位差。 弹性部55在齿轮1的端面之间形成有压力室66，用于经由加压油导入路径53将压力油室65内的加压油引入压力室66.由于弹性部55被按压 通过在宽范围内的弹力和通过压力室66和滞后角油压室62的压力差朝向叶片部分9（c），内部泄漏密封性能得到改善。 此外，由于通过弹性力的负荷不局部集中，所以密封板50的耐久性提高。 版权所有（C）2011，JPO＆INPIT
