Abstract:
A mechanism provides high pressure fluid to a cam phaser on demand. The mechanism includes a positive displacement pump within the camshaft which is driven by a pin to compress and trigger fluid to be dispensed to the phaser.

Claim (Index 9):
A variable cam timing system for an internal combustion engine comprising:\n a hollow camshaft having a first end and a second end, an outer circumference and an inner circumference defining a volume of fluid, the second end of the camshaft coupled to a phaser; a shift collar received on the outer circumference of the camshaft, connected to the camshaft through a connecting pin, the shift collar having at least one helical track for receiving a driven pin; and a hydraulic pump comprising:\n an outer piston slidably received within the inner circumference of the camshaft, the outer piston having a body with a first end and a second end, the body defining an interior; \n a check valve housing within the inner circumference of the camshaft comprising:\n a first check valve in fluid communication with a volume defined between the second end of the outer piston and the check valve housing through a first passage; and \n a second check valve in fluid communication with the volume and the phaser through a second passage; \n \n a second spring between the check valve housing and the outer piston; \n wherein the shift collar shifts from a first position to a second position, the driven pin rides in the at least one track helical track, the connecting pin pushes against the outer piston, such that fluid in the volume is elevated to a pressure; when the driven pin is in the helical track in the second position, fluid in the volume is expressed through the second check valve to the phaser at the elevated pressure.
