摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjustment device that prevents an unlocking failure of a vane rotor due to an operation failure of a stopper pin at the start of an engine.SOLUTION: The valve timing adjustment device restrains a housing and the vane rotor by engaging the stopper pin stored in a storage hole of the vane rotor with an engagement hole of the housing at engine start-up. After the engine start-up, an ECU inputs to a hydraulic control valve, a holding duty ratio at which hydraulic fluids of the same pressure are supplied to an advance angle chamber and a delay angle chamber (S106). It is determined whether the time needed for 720° rotation of a crankshaft has passed after the time when the holding duty ratio is input (S107). In the time, the direction of combined torque of advance angle hydraulic torque, delay angle hydraulic torque, and cam torque acting on the vane rotor becomes a delay angle direction, so that the stopper pin and engagement hole do not come in contact with each other.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjustment system preventing the unlocking failure and locking failure of a vane rotor.SOLUTION: In S102, when it is determined that time difference between first time when an instruction for setting intake valve opening/closing timing as desired opening/closing timing is input into an ECU and scheduled time when hydraulic pressure is adjusted by a pressure regulating valve is smaller than predetermined time, pressure of oil before and after adjustment by the pressure regulating valve is calculated as hydraulic pressure before adjustment and hydraulic pressure after adjustment, in S103. Next, in S104, it is determined whether the hydraulic pressure before adjustment is lower than start failure lower limit hydraulic pressure P1. Then, in S105, it is determined whether the hydraulic pressure after adjustment by the pressure regulating valve is lower than start failure upper limit hydraulic pressure P2. When it is determined that the hydraulic pressure before adjustment is lower than the start failure lower limit hydraulic pressure P1 and the hydraulic pressure after adjustment is lower than the start failure upper limit hydraulic pressure P2, the scheduled time for adjusting the hydraulic pressure is delayed by the predetermined time with respect to the first time, in S106.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjustment system adjusting desired valve opening/closing timing with excellent responsiveness and with precision.SOLUTION: In S101, an engine operating condition is detected. Next, in S102, it is determined whether the rotational phase of a camshaft with respect to a crankshaft is in an advance operation or a retard operation. When the rotational phase of the camshaft is in the advance operation or the retard operation, in S103, target arrival time as time required for the rotational phase of the camshaft to reach a target phase is calculated. Then, in S104, it is determined whether the calculated target arrival time is not less than predetermined target time. When it is determined that the target arrival time is not less than the predetermined target time, in S105, pressure of oil to be supplied to a phase adjustment part is set higher. Thereby, the rotational phase of the camshaft is changed to the target phase in a short period of time.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device for preventing the occurrence of lock release failure of a vane rotor by operational failure of a stopper pin upon starting an engine.SOLUTION: This valve timing adjusting device regulates relative rotation of a housing and the vane rotor by fitting the stopper pin stored in a storage hole of the vane rotor to a fitting hole of the housing when starting the engine. When releasing fitting of the stopper pin after starting the engine, an ECU compares the tension direction of acting on a rear plate for constituting the housing by a chain with the direction of a parallel component to the tension direction in the advancing direction of the storage hole (S105). When the tension direction and the direction of the parallel component are the same direction, the direction of acting on the vane rotor by a cam torque is determined (S108). When the direction of acting on the vane rotor by the cam torque and the tension direction are the opposite direction, the ECU commands generation of hydraulic pressure to a hydraulic control valve.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjustment system which can suppress the release failure of the regulation of a relative turn between a housing and a vane rotor.SOLUTION: An electronic control device 102 for the valve timing adjustment system 12 determines whether inflow pressure exceeds an upper limit in a regulation releasable pressure region if relative turn regulation is not released when a specific time elapses after opening and closing timing adjustment control during relative turn regulation is started. When the determination is made, the electronic control device 102 lowers the pressure of the hydraulic oil of advance angle hydraulic chambers 34-38 by actuating a relief valve 98 so that inflow pressure is lowered. Accordingly, since torque acting on a vane rotor 52 is reduced and a lock pin 64 easily comes off from a fitting recess 46 of the housing 16, the relative turn regulation between the housing 16 and the vane rotor 52 can be released.
摘要翻译：要解决的问题：提供一种能够抑制壳体与叶片转子之间的相对转动的调节释放故障的气门正时调节系统。解决方案：用于气门正时调整系统12的电子控制装置102确定在规定可释放压力区域中的流入压力是否超过在打开和关闭定时调整控制之后经过特定时间时相对转动调节不相应的流量压力在相对转弯调节期间开始。当进行确定时，电子控制装置102通过致动安全阀98以降低流入压力来降低提前角液压室34-38的液压油的压力。因此，由于作用在叶片转子52上的扭矩减小，并且锁定销64容易从壳体16的嵌合凹部46脱落，能够释放壳体16与叶片转子52之间的相对转动调节。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent an offset in the transmission of driving force in the peripheral direction when tensile force acts as the driving force between coaxially arranged shafts connected by a shaft connecting device. SOLUTION: Two connecting members 20 and 22 allow respective annular abutting surfaces 20f and 22f to abut over the whole periphery on annular planes 2a and 2b of flange parts 3a and 3b of the respective shafts 6 and 10. Thus, the connecting members 20 and 22 can abut without offset in the peripheral direction on the flange parts 3a and 3b, and can prevent the offset in the peripheral direction in the transmission of the driving force in the tensile direction between the connecting members 20 and 22 and the flange parts 3a and 3b. The mutual connecting members 20 and 22 can prevent the offset in the peripheral direction in the transmission of the driving force even in a coupler, due to being integrated as the coupler by joining over the whole periphery of the shaft periphery of the shafts 6 and 10.
