  • Patent number: 9080471
    Abstract: A cam torque actuated variable cam timing phaser can include a rotor (20) enclosed by an endplate (64) within a housing (10). The housing (10) can have at least one cavity (10a) to be divided by a vane (22) rigidly attached to the rotor (20). The vane (22) can divide the cavity (10a) into a first chamber (16) and a second chamber (18). Passages (26, 28, 56, 58) can connect the first and second chambers (16, 18) facilitating oscillation of the vane (20) within the cavity (10a). A detent valve (50) can move between an open position and a closed position. When in the open position, the detent valve (50) can connect portions of a detent passage (56, 58) extending through the rotor (20) and through the endplate (64) allowing pressurized actuating fluid flow with respect to the first and second chambers (16, 18) in response to a relative angular position of the rotor (20) with respect to the endplate (64). A lock pin (60) can move between a locked position and a released position.

  • Patent number: 7568458
    Abstract: A variable cam timing system for an engine with at least one camshaft comprising: a housing, a rotor, and a controlled bypass. The housing has an outer circumference for accepting drive force and chambers. The rotor has a connection to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating a chamber in the housing into advance and retard chambers. The vane is capable of rotation to shift the relative angular position of the housing and the rotor. The controlled bypass provides fluid communication between the chambers. When the valve is closed, the valve blocks passage between the chambers and when the valve is open fluid flows through the passage extending between the advance chamber to the retard chamber. A method for reducing the valve event is also disclosed.

  • Patent number: 6814037
    Abstract: A variable camshaft timing system having a camshaft with a vane-type rotor, where oscillation of the housing relative to the vane is actuated by pressurized engine oil, derived in part from a torque pulse in the camshaft. An annular locking plate is positioned coaxially with the camshaft and the housing. It is moveable relative to the housing along the longitudinal central axis of the camshaft between two positions, the teeth on the locking plate engaging the teeth on the housing and where the teeth on the locking plate are disengaged from the teeth on the housing, each position preventing circumferential movement of the housing relative to the rotor. The locking plate is biased by a plurality of metallic straps towards engagement of the teeth on locking plate with the teeth on the housing. The straps have one end secured to the locking plate and another end secured to the rotor.

  • Patent number: 6729283
    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).

  • Patent number: 6666181
    Abstract: A phaser which includes a housing and a rotor disposed to rotate relative to each other is provided. The housing has at least one cavity disposed to be divided by a vane rigidly attached to the rotor. The vane divides the cavity into a first chamber and a second chamber. The phaser further includes passages connecting the first and the second chamber, thereby facilitating the oscillation of the vane within the cavity. The phaser includes: a) a valve disposed to form at least two openings for fluid flowing between the first chamber and the second chamber and being disposed to keep at least one opening closed; and b) at least one by-pass disposed to stop or slow down the rotation between the housing and the rotor, thereby allowing a locking mechanism to lock the housing and the rotor together independent of fluid flow.
