<p>A variable cam timing phaser (10) can a drive stator (14) and at least one driven rotor (20, 20a, 20b) mounted for rotation about a common axis. At least one vane-type hydraulic coupling can define at least one expandable fluid chamber (40, 50, 40a, 50a, 40b, 50b) for coupling the at least one driven rotor (20, 20a, 20b) for rotation with the drive stator (14) to enable the phase of the at least one driven rotor (20, 20a, 20b) to be adjusted independently of one another and independently relative to the drive stator (14). A control valve (60) can have at least one inlet port (62), at least one outlet port (64, 64a), and at least one common shared fluid passage (16, 16a, 16b, 16c, 16d). At least one rotatable fluid flow diverter (80, 80a) can be in fluid communication with the at least one common shared fluid passage (16, 16a, 16b, 16c, 16d) for selectively communicating the at least one common shared fluid passage (16, 16a, 16b, 16c, 16d) with the at least one expandable fluid chamber (40, 50, 40a, 50a, 40b, 50b).</p> |
