摘要： A hydraulic apparatus for adjusting the timing of opening and closing of an engine valve includes a cam shaft driven to rotate in synchronization with the engine rotation. An actuator is installed on the cam shaft for changing the timing of opening and closing of an intake valve and/or exhaust valve using a control of a working oil supply. A slidable plunger is disposed in the actuator, and a rotor is disposed in the actuator to engage with the plunger by an engaging hole. A spring urges the plunger to move into the engaging hole to make an engagement therebetween when the engine is stopped, and when the engine begins to run, the working oil is supplied into the engaging hole to push out the plunger from the engaging hole to release the engagement between a housing of the actuator and the rotor. The engaging hole and the plunger have a surface parallel with a slide direction of the plunger, and a clearance therebetween is smaller than 0.17 mm when the engaging hole and plunger engage each other.

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.
