Abstract:
1. A camshaft phaser comprising: a drive element; a first driven element; and a second driven element, each of the drive and first and second driven elements being arranged coaxially to a rotational axis of the camshaft phaser, each of the first and second driven elements and the drive element having several radially oriented vanes forming working chambers, each working chamber being defined by a vane pair defined by a vane of the drive element and a vane of one of the first and second driven elements, the working chambers pressurizable by a hydraulic medium so that a relative rotation is made possible between the drive element and the associated first or second driven element, the first and second driven elements being arranged axially one after the other in such a way that a vane of the first driven element extends in the axial direction along a lateral surface of the second driven element, and a vane of the second driven element extends in an axial direction along a lateral surface of the first driven element.
