Abstract: A variable camshaft timing (VCT) control valve assembly includes: a control valve having one or more lands and a valve cavity; one or more cavity vents in the control valve are configured to communicate fluid between an outer surface of the control valve and the valve cavity; a valve sleeve having a sleeve cavity that receives the control valve and a plurality of apertures, at least one of the apertures is configured to be in fluid communication with an advance fluid chamber of a VCT device and another of the apertures is configured to be in fluid communication with a retard fluid chamber; the control valve slides axially relative to the valve sleeve; and one or more reed valves, attached to an outer surface of the valve sleeve, configured to control the flow of fluid between one of the advance fluid chamber or the retard fluid chamber and the other of the advance fluid chamber or the retard fluid chamber.

Abstract: A spool valve assembly, configured to control the flow of fluid, includes a spool valve, configured to move axially along an axis to control fluid flow, having a spool cavity and a plurality of spool apertures that communicate fluid between the spool cavity and an outside surface of the spool valve; a valve sleeve, in which the spool valve is concentrically positioned, that slidably receives the spool valve; and a valve plug, received within the spool cavity, having at least one plug aperture and a plug cavity, wherein the spool apertures at least partially overlap the plug aperture(s) in a radial direction to permit the flow of fluid between the plug cavity and the outside surface within a defined flow rate variance regardless of the angular position of the valve plug relative to the angular position of the spool valve.

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.
