Webs on the stator, divide an annular space between the stator and the rotor into pressure chambers, wherein the rotor has a rotor hub and vanes extending radially outward from the rotor hub, which vanes divide the pressure chambers into two groups of working chambers having a different acting direction, into each of which working chambers pressure medium flowing in or out in a pressure-medium circuit can be admitted, and a central locking device for locking the rotor in relation to the stator. The central locking device has two spring-loaded locking pins in an accommodating space, and lockable in a locking slot-secured to the stator and lock in the locking slot when the rotor rotates from the direction of an “early” or “late” stop position into the locking position from different directions, wherein the locking pin forms a valve device together with the particular accommodating space, wherein the locking pin is a step pin.

摘要： A variable valve actuation device for an internal combustion engine includes a variable valve timing mechanism and a valve timing restricting mechanism. When the operating state of the variable valve timing mechanism is in the phase restricting state and the operating state of the variable valve timing mechanism is changed to the phase releasing state on the basis of pressing the accelerator pedal, a torque limiting control is then performed to limit an increase in the torque of the internal combustion engine. With this control the rate of increase of the torque is set less than the rate of increase of the torque corresponding to the operation of pressing the accelerator pedal by retarding and correcting the ignition timing. Thus, when the operating state of the variable valve timing mechanism is changed from the phase restricting state to the phase releasing state, thereby reducing discomfort experienced by the driver.

摘要： A control device projects a lock pin to lock a VCT phase in an intermediate lock phase when a lock request occurs. A learning unit learns one of a most retarded phase, a most advanced phase, and an intermediate lock phase, as a reference phase. A control unit sets a target phase according to the reference phase and controls the control device. A monitor unit determines that the VCT phase has passed through the intermediate lock phase when the lock request occurs before completion of learning of the reference phase, and when a change in the VCT phase becomes greater than a threshold. The threshold is set to be greater than a sum of i) a design value of a phase difference between the intermediate lock phase and one of the most retarded phase and the most advanced phase and ii) a range of a product variation of the phase difference.
