F01L 1/344

A hydraulically-actuated variable camshaft timing (VCT) system comprises a spool valve including a sleeve and a spool, having a plurality of radially-outwardly extending lands, received within the sleeve; a first fluid supply port in the sleeve configured to receive fluid from a fluid supply; a second fluid supply port in the sleeve configured to receive fluid from the fluid supply; an advancing port in the sleeve in fluid communication with an advancing chamber of a hydraulically-actuated camshaft phaser; a retarding port in the sleeve in fluid communication with a retarding chamber of the hydraulically-actuated camshaft phaser; and an exhaust port axially positioned in the sleeve in between the first fluid supply port and the second fluid supply port or in between the advancing port and the retarding port, wherein the exhaust port is configured to selectively receive fluid from either the advancing chamber or the retarding chamber depending on an axial position of the spool relative to the sleeve.

F01L 1/356
F01L 1/047

A variable camshaft timing (VCT) system includes an independent camshaft phaser, receiving input from a crankshaft of an internal combustion engine, having an output coupled to one of an inner concentric camshaft or an outer concentric camshaft; and a dependent camshaft phaser, coupled to the other of the inner concentric camshaft or the outer concentric camshaft, comprising a half-Oldham link configured to permit radial movement of the inner concentric camshaft relative to the outer concentric camshaft in one radial direction and at least one pivotable arm configured to permit radial movement of the inner concentric camshaft relative to the outer concentric camshaft in another, different radial direction.

F01L 1/344

A hydraulically-actuated variable camshaft timing (VCT) system comprises a spool valve including a sleeve and a spool, having a plurality of radially-outwardly extending lands, received within a sleeve; a sleeve fluid pathway, extending axially along the sleeve and formed within the sleeve, configured to receive fluid from a fluid supply; an advancing port in the sleeve in fluid communication with an advancing chamber of a hydraulically-actuated camshaft phaser; a retarding port in the sleeve in fluid communication with a retarding chamber of the hydraulically-actuated camshaft phaser; a first fluid supply port formed in the sleeve; a second fluid supply port formed in the sleeve; and an exhaust port axially positioned in the sleeve in between the first fluid supply port and the second fluid supply port or in between the advancing port and the retarding port, wherein the exhaust port is configured to selectively receive fluid from either the advancing chamber or the retarding chamber depending on an axial position of the spool relative to the sleeve.

F01L 1/344

A phaser which has an offset or remote pilot valve added to the hydraulic circuit to manage a hydraulic detent switching function, in order to provide a mid-position lock for cold starts of the engine, either during cranking or prior to complete engine shutdown. The mid-position locking of the phaser positions the cam at an optimum position for cold restarts of the engine.

F01L 1/344
F01L 1/047

A variable camshaft timing (VCT) assembly for controlling angular positions of concentric camshafts. The VCT assembly includes an independent VCT device and a dependent VCT device. The independent VCT device is hydraulically- or electrically-actuated. The independent VCT device is coupled with a first concentric camshaft and has a first component that rotates during phasing movements. The first component has a first set of slots therein. The dependent VCT device is coupled with a second concentric camshaft. The dependent VCT device has a second component that lacks rotation during phasing movements, and has multiple phase lugs. The second component has a second set of slots therein. The phase lugs are received in the first set of slots and are received in the second set of slots.

F01L 1/02

A pulley for phaser including a toothed outer circumference for accepting a drive force; an inner circumference with at least a first set of lands extending towards a center of the pulley and spaced apart along the inner circumference of the pulley; and an axial retaining feature on the first set of lands for interaction with a corresponding retaining feature of a housing press fit within the inner circumference with the pulley, axially retaining the housing within the pulley.
