摘要： A cam shaft phaser, including: a stator including stops; a rotor rotatable with respect to the stator and including a plurality vanes extending radially outward from a body; a plurality of channels, each channel passing through a respective vane included in the plurality of vanes; and a plurality of pairs of advance and retard chambers at least partially formed by the plurality of radially inwardly extending stops and the plurality of vanes. Advance and retard chambers for each pair of advance and retard chambers are separated in a first circumferential direction by a respective vane from the plurality of vanes. Each channel connects the advance and retard chambers for said each pair of advance and retard chambers. The first plurality of channels are arranged to enable fluid flow through the first plurality of channels to displace the rotor from at least one circumferential position to a mid-lock or retard-lock position.

摘要： In a hydraulically-operated vane rotor equipped variable valve timing control device for an internal combustion engine, a fluid-communication control mechanism is configured to switch, after having started the engine, a communication hole from a communicated state to a fluid-communication restricted state prior to switching operation of a lock mechanism from a lock state in which rotary motion of a vane rotor relative to a housing is restricted to an unlock state in which rotary motion of the vane rotor relative to the housing is enabled. As a result of this configuration, it becomes possible to apply, after having started the engine, an appropriately controlled hydraulic pressure to all of vanes, with hydraulic pressure supplied to either all phase-retard chambers or all phase-advance chambers, thereby ensuring a good control responsiveness of the vane rotor.

摘要： A valve timing control apparatus has a regulation member to fix a phase. The regulation member has a main regulation member and a sub regulation member. The main regulation member is inserted into a recess part to regulate the phase. The sub regulation member has an engagement part engageable with the main regulation member in an escape direction Y and disengageable from the main regulation member in an insertion direction X. Further, the sub regulation member has a pressure reception part that receives pressure in the escape direction Y from hydraulic fluid in an operation chamber. The main regulation member is urged in the insertion direction X by a main resilient member. Further, the sub regulation member is urged in the insertion direction X by a sub resilient member. The main regulation member moves in the escape direction Y only by hydraulic fluid, and moves in the insertion direction X only by the resilient member.

摘要： A hydraulic camshaft adjuster for changing the control times of gas exchange valves of an internal combustion engine, designed as a vane cell camshaft adjuster. A control device inserted in the vane selectively opens and interrupts a flow connection between the working chambers. A locking device prevents relative motion between the rotor and the stator in that the rotor is fastened to the stator at a vane position. A switching valve, which has three working ports, a P port and a T port, can be moved into different control positions by an adjusting element,—wherein in the control position, the P port communicates with the working chambers via the A port, the B port is blocked at the switching valve, and the T port communicates with the control device of the vanes via the C port. In a control position provided as a starting strategy for the switching valve the A port communicates with the P port and the working chambers, the B port communicates with the T port and the working chambers, and the C port communicates with the control device of the vanes and the T port.

摘要： A variable valve timing control apparatus includes a driving-side rotation member, a driven-side rotation member, an intermediate lock mechanism including first and second lock members, first and second recess portions, and a guide groove, a sensor, and a control portion. The control portion performs a control so that the relative rotation phase is changed until a first stop state is established in a state where the relative rotation phase is in an unlocked state and one of the first and second lock members is positioned relative to one of the first and second recess portions at which the guide groove is formed at a side opposite from a side where the guide groove is formed. The control portion reverses a change direction of the relative rotation phase after the first stop state is established so that the relative rotation phase is changed until a second stop state is established.

When working fluid is discharged from the intermediate lock mechanism, and working fluid is supplied to the advancing chamber and is discharged from the retarding chamber, the maximum working fluid flow amount through the advancing and retarding channels is greater than the maximum working fluid flow amount through the advancing and retarding channels when the electromagnetic valve is controlled such that the working fluid is supplied to the intermediate lock mechanism.
