A camshaft phaser arrangement configured for a concentric camshaft assembly having inner and outer camshafts is provided. The camshaft phaser arrangement includes a first camshaft phaser, a second camshaft phaser, and a coupling that non-rotatably connects the first camshaft phaser to the concentric camshaft assembly. Each of the camshaft phasers is configured to be connected to either the inner or the outer camshaft. The coupling accommodates for radial and axial offset between the first camshaft phaser and the second camshaft phaser.

Coupling for a camshaft phaser arrangement for a concentric camshaft assembly

In one embodiment, a valve arrangement is disclosed. The valve arrangement includes a housing defining a chamber, and the housing includes a plurality of ports. A first valve assembly includes a first valve body arranged and a second valve assembly includes a second valve body. A gear arrangement is configured to drive the first valve body in a first rotational direction and is configured to drive the second valve body in a second rotational direction, and the second rotational direction is opposite from the first rotational direction.

Valve arrangement

In one embodiment, a thermal management module is disclosed that includes: a housing defining a plurality of ports and at least one camshaft opening, the housing defining at least one chamber; a camshaft extending through the at least one camshaft opening into the chamber, the camshaft including a plurality of cams; a plurality of seal assemblies each surrounding a respective port of the plurality of ports; and a plurality of stoppers each arranged with a respective port of the plurality of ports. In one aspect, at least one port of the plurality of ports includes a guidance finger adapted to guide a respective stopper of the plurality of stoppers. In another aspect, openings defined by at least two ports of the plurality of ports overlap in an axial direction of the openings.
