Abstract: A valve assembly that can be employed in a variable camshaft timing (VCT) phaser assembly. The valve assembly includes a metal sleeve and a check valve. The check valve, in an implementation, has an integral construction with the metal sleeve. The integral construction has multiple designs, one of which includes an overmolded construction of the check valve with the metal sleeve. The valve assembly can also include a valve housing which, in the implementation of the VCT phaser assembly, is a center bolt.

Abstract: 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.

Abstract: A variable camshaft timing device can operate using pressure generated by camshaft torque energy to transfer fluid from one working chamber to another work chamber or operate via an external fluid pressure source to fill one working chamber while simultaneously exhausting an opposing working chamber or operate using both modes simultaneously. The mode of the variable camshaft timing device is determined by the position of the control valve. The lock pin is controlled by fluid from one of the working chambers.

Abstract: 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.
