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 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 includes a stator having a plurality of lobes; a rotor coaxially disposed within the stator and having a plurality of vanes interspersed with the lobes defining advance chambers and retard chambers; a camshaft phaser attachment bolt for attaching the camshaft phaser to a camshaft, the camshaft phaser attachment bolt defining a valve bore that is coaxial with the stator. A supply passage extends radially outward from the valve bore and includes a downstream end that is proximal to the valve bore and an upstream end that is distal from the valve bore and separated from the downstream end by a check valve seat. A check valve member in the supply passage is biased toward the check valve seat by centrifugal force. A valve spool is moveable within the valve bore such that the valve spool directs oil that has passed through the supply passage.

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 is disposed within the stator includes vanes interspersed with the stator lobes to define alternating advance and retard chambers. A lock pin is provided for selective engagement with a lock pin seat for preventing relative rotation between the rotor and the stator. Pressurized oil disengages the lock pin from the seat while oil is vented for engaging the lock pin with the seat. A phase relationship control valve is coaxial with the rotor and controls the flow of oil into and out of the chambers. A lock pin control valve is coaxial with the phase relationship control valve and controls the flow of oil to and from the lock pin. The control valves are operational independent of each other.
