摘要： A valve timing control device includes a purge path communicating between a hydraulic chamber allowing the entry of hydraulic pressure on starting an engine and a backward pressurized section in an accommodation hole. When the hydraulic chamber allowing the entry of hydraulic pressure on starting the engine is the retardation side hydraulic chamber, a hydraulic pressure derived from an oil pump is supplied to the retardation side hydraulic chamber on starting the engine. On the way, air-mixed oil is discharged to outside of the device by way of a purge path, a backward pressurized section in the accommodation hole and the discharge hole. When the air is discharged, a residual pressure is produced in the backward pressurized section due to oil supplied thereto. The residual pressure results in the increase of an unlocking hydraulic pressure to prevent a locking member from being unlocked. When the application of a retardation side hydraulic pressure is switched to that of an advance side hydraulic pressure, the pressure presses a front end of a locking member against only a biasing force of a biasing means to unlock a locking relation. The valve timing control device allows the use of any kinds of locking pins, and prevents the occurrence of beat noise (abnormal noise) when air-mixed oil unlocks a locking relation on starting the engine.

摘要： A valve timing control device has a lock pin for controlling the rotation between first and second rotors. A purge valve is arranged at the lock pin, the purge valve discharging air-mixing oil into a discharge hole in a release operation. On application of first pressure of release hydraulic pressure, a part of the first pressure is discharged through the purge valve, a backward pressure chamber and the discharge hole to the outside the device. Therefore, the lock pin is slid to reduce applied pressure, and it can delay a release operation to prevent the occurrence of beat noise on starting an engine.

摘要： A valve timing control device has a hydraulic pressure supply passage for supplying a hydraulic pressure used for releasing lock due to the lock member. If a hydraulic pressure applied to the hydraulic pressure supply passage reaches a required pressure, a hydraulic pressure subjected to a major diameter section of the lock member is larger than the sum total of the biasing force of two biasing members. Thus, the lock member is returned in a direction of releasing the lock due to the lock member. The sliding member is moved backward while the lock member is also moved backward. The stroke of the sliding member is extremely shorter than that of the lock pin. With a locked state of leaving the engagement of a minor diameter section of the lock member with an engagement hole, a rear end face of a minor diameter section of the sliding member abuts with a rear wall face 16c of a backward pressure chamber. Thus, it is difficult that a backward pressure space defined between the lock member and the sliding member communicates with a discharge hole. Since the opening area of the discharge hole substantially is throttled, a speed of discharging the backward pressure is considerably delayed.
摘要翻译：气门正时控制装置具有液压供给通道，用于提供用于由锁定构件释放锁定的液压。如果施加到液压供给通道的液压达到要求的压力，则经受锁定构件的大直径部分的液压压力大于两个偏置构件的偏置力的总和。因此，锁定构件在由锁定构件释放锁定的方向返回。当锁定构件也向后移动时，滑动构件向后移动。滑动构件的行程比锁定销的行程短得多。在锁定状态下，锁定构件的小直径部分的接合具有接合孔，滑动构件的小直径部分的后端面与后向压力室的后壁面16c抵接。因此，限定在锁定构件和滑动构件之间的向后压力空间难以与排出孔连通。由于排出孔的开口面积基本上被节流，所以后退压力的排出速度显着延迟。
