Abstract: A locking device is provided to lock the phaser vane and sprocket together at all times except when the phaser is moving from position to position. The locking device ensures that the phaser is locked for start conditions and ensures the prevention of noise from being generated. The locking device also ensures that the timing accuracy of the phaser is controlled at a number of positions for the steady state condition.

Abstract: An internal DPCS feeds (13) engine oil pressure (32) to one side (19) of the spool and a solenoid controlled pressure (14) to a piston (12) that has twice the area as that side (19) of the spool. The spool end (21) that is fed control pressure is preferably twice the area of the spool end (19) that is fed with engine oil pressure. A spring (18) mounted in the phaser pushes the spool (25) to the default position in case of solenoid failure. A PWM solenoid valve (15) or a proportional solenoid valve controls the oil flow to the large area end (21) of the spool (25). In a preferred embodiment of the invention, a position sensor (34) further controls the position of the spool valve (28).

Abstract: The present invention controls the position of a center mounted spool valve (192) with an externally mounted vacuum controlled actuator (301). The actuator position is preferably controlled by a pulse width modulated or variable force solenoid (302), which modulates the amount of vacuum going to the actuator (301). A microprocessor (208) reads the phase angle and adjusts the duty cycle or current based on the error signal of the control loop (450). In a preferred embodiment, a position sensor (304) further controls the position of the spool valve (192). The position sensor (304) creates an inner loop (400) with position feedback on the position of the actuator (301) and spool valve (192), while the outer loop controls the phase angle. Added to the spool valve position is an offset to move the spool valve (192) to its steady state or null position (410).

Abstract: A lock mechanism for a phaser of a variable cam timing system is actuated by an electromagnetic force. Since the lock mechanism is not dependent upon engine oil pressure, it is actuatable at any time from engine startup to engine shutdown. A lock solenoid is preferably used to actuate a lock pin, which is otherwise urged toward a lock hole and a locked position by a spring force, to an unlocked position. The lock solenoid preferably acts on a pin lock plate that is coupled to the lock pin. A preferred startup method and a preferred shutdown method are also described.

Abstract: A variable camshaft timing system for an internal combustion engine comprising a housing having an outer circumference for accepting drive force, a rotor for connection to a camshaft coaxially located within the housing capable of rotation to shift the relative angular position of the housing and the rotor, a locking pin, and a centrifugal valve. The locking pin is slidably located and radially moveable in a radial bore from a locked position in which the inner end fits into the recess defined by the housing, locking the relative angular position of the rotor and housing, to an unlocked position in which the inner end does not engage the receiving hole defined by the housing. The centrifugal valve is in fluid communication with an inlet line coupled directly to an engine oil supply controlling flow of oil to the locking pin.
