Multi-camshaft phase adjusting system

A camshaft phaser arrangement configured for adjusting a phase between a first camshaft element and a second camshaft element, the camshaft phaser arrangement comprising:

• a stator configured to be drivably connected to a crankshaft;
• a rotor configured to be drivably connected to the first camshaft element, the rotor being configured to be selectively rotationally driven such that rotation of the rotor is configured to phase the first camshaft element;
• a first and second cover arranged on respective axial sides of the rotor and the stator to partially define hydraulic chambers;
• and
• a phasing adjuster configured to pivot based on rotation of the rotor, the phasing adjuster including a first engagement element configured to engage with a second engagement element on the second camshaft element, such that rotation of the rotor is configured to phase the second camshaft element via the phasing adjuster;
• wherein the first camshaft element and the second camshaft element are arranged concentrically with each other, and wherein at least one of the first or second covers includes a through slot dimensioned to receive a pin attached to the rotor, and the pin is configured to travel within a groove on the phasing adjuster to phase the second camshaft element.
