Systems and methods for a cam phasing control system are provided. In particular, systems and methods are provided for a cam phasing control system that can be configured to control a first cam phase actuator and a second cam phase actuator and selectively switch the operation thereof between a regenerative mode and an oil pressure actuation mode.

A yoke-type phaser is disclosed having a drive member and a driven member rotatable about a common axis and coupled to one another by means of a yoke that is movable, in a plane normal to the common axis, to vary the relative phase of the drive and driven members, by interaction between at least two contact elements and a contoured surface, one of (i) the contact elements and (ii) the contoured surface being connected for rotation with the drive member and the other being mounted on the yoke, each contact element comprising a roller in surface contact with a part-cylindrical recess in a carrier, wherein the carrier of at least one of the contact elements is either appropriately sized or adjustably mounted, to set the clearances between the rollers and the contoured surface.
