Abstract: A camshaft phaser includes a stator; a rotor defining an advance chamber and a retard chamber with the stator; a valve spool that is rotatable about an axis and defining a supply chamber and a vent chamber with the rotor; an actuator which rotates the valve spool to change the position of the rotor relative to the stator by 1) supplying oil from the supply chamber to the advance chamber and venting oil from the retard chamber to the vent chamber and 2) supplying oil from the supply chamber to the retard chamber and venting oil from the advance chamber to the vent chamber; and a check valve which is displaceable axially between an open position which allows oil to flow from the vent chamber to the supply chamber and a closed position which prevents oil from flowing from the supply chamber to the vent chamber.

Abstract: A camshaft phaser includes a stator having lobes and a rotor disposed within the stator having vanes interspersed with the lobes. A lock pin disposed within one of the rotor and the stator selectively engages a seat for preventing relative rotation between the rotor and the stator when the lock pin is engaged with the seat. A bolt extends coaxially through the rotor and the stator to attach the camshaft phaser to a camshaft. A valve spool in the bolt controls the flow of oil to and from the lock pin. The bolt includes a supply drilling extending therethrough to supply pressurized oil to the valve spool.

Abstract: A camshaft phaser includes a stator having a plurality of lobes and a rotor coaxially disposed within the stator and having a plurality of vanes interspersed with the lobes defining a plurality of alternating advance chambers and retard chambers such that a phasing valve supplies and vents oil to and from the advance and retard chambers. A first check valve allows oil to flow from only one of the retard chambers to only one of the advance chambers when a first diverter valve permits communication between the one of the advance chambers and the first check valve and a second check valve allows oil to flow from the one of the advance chambers to the one of the retard chambers when a second diverter valve permits communication between the one of the retard chambers and the second check valve.

Abstract: A camshaft phaser is provided for varying the phase relationship between a crankshaft and a camshaft in an engine. The camshaft phaser includes a stator having lobes. A rotor disposed within the stator and rotatable between a full retard position to a full retard position includes vanes interspersed with the stator lobes to define alternating advance and retard chambers. A lock pin selectively engages a lock pin seat for preventing a change in phase relationship between the rotor and the stator at a predetermined aligned position between the full advance and full retard positions. A counterbalancing member is located within one of the advance chambers or the retard chambers, attached to a vane to thereby apply a torque between the rotor and the stator only when the rotor is between the predetermined aligned position and one of the full retard position and the full advance position.
