A cam phaser including a rotation phaser and a hydraulic valve hydraulically loading the rotation phaser, wherein the hydraulic valve is connectable torque proof with a cam shaft so that the cam shaft is rotatable, wherein the rotation phaser includes a stator and a rotor configured coaxial with the stator, wherein the rotor is rotatable relative to the stator, wherein the hydraulic valve is configured so that it protrudes at least partially into the rotation phaser, wherein an adapter is provided for a relative axial positioning of the rotor and the stator. According to the invention the adapter is configured for loose mounting in the rotation phaser so that a fixated connection of the adapter in the rotation phaser is provided when the cam shaft is mounted at the hydraulic valve.

Cam phaser

A valve timing control device, in effect a cam phaser, for an internal combustion engine. The valve timing control device includes a rotor connected to a camshaft and having a plurality of vanes. A stator is engaged with the rotor, and includes a plurality of webs. Pressure chambers are provided between each of the webs and vanes. The cam phaser is configured to automatically locate to its mid-lock position, without having to rely on electronic control. At least one embodiment of the present invention is configured to use cam torque to recirculate oil from one side of the vanes of the rotor to the other.

Mid lock directional supply and cam torsional recirculation

A valve timing control device for an internal combustion engine. The valve timing control device includes a rotor connected to a camshaft and having a plurality of vanes. A stator is engaged with the rotor, and includes a plurality of webs. Pressure chambers are provided between each of the webs and vanes. A centering slot is provided on the stator and/or the rotor. A pressure medium control valve is disposed in one of the vanes of the rotor, and is configured to not only selectively lock and unlock the position of the rotor relative to the stator, but is also configured such that pressure medium in the pressure chambers is ventable through the centering slot and thereafter through the pressure medium control valve.

Centering slot for internal combustion engine

A valve timing control device for an internal combustion engine. The valve timing control device includes a rotor connected to a camshaft and having a plurality of vanes. A stator is engaged with the rotor, and includes a plurality of webs. Pressure chambers are provided between each of the webs and vanes. A centering slot is provided on the stator and/or the rotor. A pressure medium control valve is disposed in one of the vanes of the rotor, and is configured to not only selectively lock and unlock the position of the rotor relative to the stator, but is also configured such that pressure medium in the pressure chambers is veritable through the centering slot and thereafter through the pressure medium control valve.

A valve timing control apparatus for a combustion engine according to which a rotational member, such as a sprocket, is driven by said combustion engine, a rotor is mechanically coupled with a camshaft for controlling opening and closing of cylinder valves of said combustion engine, a first configuration is provided in which the rotor is locked to the rotational member; and a second configuration is provided in which the rotor is unlocked from said rotational member. In another aspect an operating method of said valve timing control apparatus for adjusting a valve timing of a combustion engine is provided. The apparatus controls a relative rotation between a camshaft and an output shaft, which can either be prevented or permitted.
