摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device having excellent responsiveness to phase control irrespective of the pressure of a working fluid.
SOLUTION: A check valve 90 is installed in a retard-angle passage connected to a retard-angle hydraulic pressure chamber. A control valve 100 is installed in a retard-angle passage branched from the retard-angle passage. Even if a vane rotor 21 receives torque variation from a camshaft 20 when the vane rotor 21 is controlled to a target phase on the retard-angle side in the reverse direction to the pressing direction of a spring 18, a hydraulic oil is prevented from flowing out of the retard-angle hydraulic pressure chamber in which the check valve 90 is installed. The hydraulic oil is prevented from flowing out of the other retard-angle hydraulic pressure chambers by preventing the hydraulic oil from flowing out of one retard-angle hydraulic pressure chamber of a plurality of retard-angle hydraulic pressure chambers. Since the vane rotor 21 is prevented from returning from a target phase to the advance-angle side during phase control, the vane rotor 21 can rapidly reach the target phase.

摘要翻译：要解决的问题：提供一种对相位控制具有优异响应性的气门正时调节装置，而与工作流体的压力无关。解决方案：止回阀90安装在连接到延迟角液压室的延迟角通道中。控制阀100安装在从延迟角通道分支的延迟角通道中。即使当叶片转子21在与弹簧18的按压方向相反的方向上的延迟角侧被控制到目标相位时，叶片转子21从凸轮轴20接收转矩变化，则防止液压油流动在其中安装有止回阀90的延迟角液压室中。通过防止液压油从多个延迟角液压室的一个延迟角液压室流出，防止液压油从其他延迟角液压室流出。由于在相位控制期间叶片转子21被防止从目标相位返回到提前角侧，因此叶片转子21能够快速达到目标相位。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device in which the wear and abnormal noise of a check valve are reduced by maintaining the opened state of the check valve when the rotational speed of a vane rotor is raised.
SOLUTION: The valve member 93 of the check valve 90 is reciprocatingly moved in the radial direction of a vane rotor 21 to open and close the clearance between an advance-angle passage 83 and an advance-angle passage 87. Therefore, when the rotational speed of the vane rotor 21 is raised and the centrifugal force applied to the valve member 93 becomes larger than the pressing force of the elastic member 95, the check valve 90 opens the clearance between the advance-angle passage 83 and the advance-angle passage 87. Even if a hydraulic pressure pulsation occurs in the hydraulic oil by the driving reaction of an intake valve applied to a camshaft 20, the movement of the valve member 93 of the check valve 90 due to the change of the hydraulic pressure is reduced. Consequently, the wear and abnormal noise of the valve member 93 and the holder 94 due to impact between the valve member 93 and the holder 94 can be reduced.

摘要翻译：要解决的问题：提供一种气门正时调节装置，其中当叶片转子的转速升高时，通过保持止回阀的打开状态来减小止回阀的磨损和异常噪声。解决方案：止回阀90的阀构件93沿着叶片转子21的径向往复移动，以打开和关闭提前角通道83和提前角通道87之间的间隙。因此，当叶片转子21的旋转速度升高，并且施加到阀构件93的离心力变得大于弹性构件95的按压力，止回阀90打开提前角通路83和提前角通路83之间的间隙。即使通过施加到凸轮轴20的进气门的驱动反作用而在液压油中产生液压脉动，由于液压变化，止回阀90的阀构件93的移动是降低。因此，可以降低由阀构件93和保持器94之间的冲击引起的阀构件93和保持器94的磨损和异常噪音。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device with high operational responsiveness by improving sealability between the valve member and the valve seat of a check valve.
SOLUTION: The valve member 93 of the check valve 90 is restricted so as not to move in the radial direction of a check valve passage 92 by abutting on the projection part 98 of a holder 94. Therefore, even if a centrifugal force is applied to the valve member 93 of the check valve 90 according to the rotation of a vane rotor 21, the valve member 93 is obstructed so as not to move in the radial direction of the vane rotor 21 by the projection part 98. Therefore, when the valve member 93 is seated on the valve seat 96, the valve member 93 is not moved by the centrifugal force, and any space is not formed between the valve member 93 and the valve seat 96. Consequently, the sealability of the check valve 90 can be improved, and hydraulic oil is prevented from leaking through the clearance between the valve member 93 and the valve seat 96.

摘要翻译：要解决的问题：通过提高止回阀的阀构件和阀座之间的密封性来提供具有高操作响应性的气门正时调节装置。解决方案：止回阀90的阀构件93被限制为不通过抵靠保持器94的突出部98而在止回阀通道92的径向方向上移动。因此，即使离心力根据叶片转子21的旋转而被施加到止回阀90的阀构件93，阀构件93被突出部98阻挡而不能沿叶片转子21的径向移动。因此，当阀构件93被安置在阀座96上时，阀构件93不被离心力移动，并且在阀构件93和阀座96之间没有形成任何空间。因此，止回阀的密封性 90可以改善，并且防止液压油通过阀构件93和阀座96之间的间隙泄漏。（C）2007年，JPO和INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device having high phase control responsiveness and requiring a smaller size selector valve for selecting a supply passage or a discharge passage.
SOLUTION: A supply selector valve 140 is change-over selectable for the communication of the supply passage 104 with a retardation supply passage 110 or the communication of the supply passage 104 with an advance supply passage 120. Check valves 111, 12 are installed in the retardation supply passage 110 and the advance supply passage 120, respectively. The check valves 111, 121 permit the supply of operating oil from an oil pump 102 to hydraulic pressure chambers and prohibit the backflow of the operating oil from the hydraulic pressure chambers to the side of the oil pump 102. A discharge selector valve 150 is formed separately from the supply selector valve 140. It is change-over selectable for the communication of a retardation discharge passage 130 with the discharge passage 134 and the communication of an advance discharge passage 132 with the discharge passage 134.

摘要： PROBLEM TO BE SOLVED: To control a rotation phase of a camshaft 2F so as to obtain target valve timing at start-up of an internal combustion engine.SOLUTION: A valve timing adjustment device includes an adjustment mechanism 1 into which a planetary gear reduction gear 60 connected to a crankshaft 16F, a camshaft 2F and a brake shaft 131 and having a predetermined reduction ratio between the camshaft and the brake shaft is incorporated, and which adjusts the valve timing by driving of the reduction gear by the crankshaft. At start-up, the brake shaft is put in a stopped state at the time t2 and the phase of the cam shaft is set so as to be estimated from a crank detection signal and driving of the adjustment mechanism 1 to an advance angle side is started. The valve timing by the estimation is calculated from the crank detection signal and the reduction ratio. At the time t3 when the calculated valve timing by the estimation reaches target valve timing, brake torque is adjusted to set the valve timing to the calculated target valve timing.

摘要： PROBLEM TO BE SOLVED: To provide a VVT capable of improving mountability, and capable of reducing the number of part items, by enhancing interlocking accuracy of an OCV and an OSV. SOLUTION: The OCV 22 supplying driving oil pressure to an ignition timing advance chamber A or an ignition timing delay chamber B, and the OSV 29 controlling opening-closing of an ignition timing advance drain control valve 25 and an ignition timing delay drain control valve 28, are arranged as one solenoid spool valve 51. Thus, reliability of the VVT can be enhanced by surely and highly accurately interlocking the OCV 22 with the OSV 29. Due to being one solenoid spool valve 51, processing manhours for installing the OCV 22 and the OSV29 can be reduced, and a mounting space of the OCV 22 and the OSV 29 can be reduced. The number of part items can be further reduced by respectively separately arranging the OCV 22 and the OSV29, and cost can be restrained. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device for increasing a working fluid flow rate supplied to an ignition timing delay chamber or an ignition timing advance chamber arranged in a partial fluid passage and connected with a phase check valve, more than a working fluid flow rate supplied to an ignition timing delay chamber or an ignition timing advance chamber connected to the other fluid passage, in at least one phase side fluid passage provided with the phase check valve among an ignition timing delay passage and an ignition timing advance passage. SOLUTION: The ignition timing delay passage 212 supplying a hydraulic fluid to the ignition timing delay chamber 51 is an exclusive passage for connecting an ignition timing delay passage 210 to the ignition timing delay chamber 51. The ignition timing delay passages 213 and 214 supplying the hydraulic fluid to ignition timing delay chambers 52 and 53 are a branch passage branching off from an ignition timing delay passage 211 being a supply passage. With this constitution, since the working fluid flow rate per unit time supplied to the ignition timing delay chamber 51 from the ignition timing delay passage 212 is increased more than a working fluid flow rate per short time respectively supplied to the ignition timing delay chambers 52 and 53 from the ignition timing delay passages 213 and 2314, the ignition timing delay chamber 51 is filled with the hydraulic fluid earlier than the ignition timing delay chambers 52 and 53.
