A camshaft phaser for the adjusting valve timing of a combustion engine includes a stator and a rotor that can rotate relative to the stator. The rotor is connected to one end of the camshaft via an adapter as well as via a sprocket which is fixedly mounted to the stator. The sprocket is slideably mounted about the camshaft with a first guiding section and is slideably mounted about the adapter with a second guiding section.

Camshaft phaser

A hydraulic camshaft adjuster () with a stator () in which a rotor () is rotatably arranged. A vane () which protrudes radially outwards is provided on the rotor (), the vane being provided with a pressure chamber delimiting side (). A pressure chamber supply groove () is arranged so as to extend on a separation plane which separates the rotor () into two halves in order to supply a hydraulic medium to a pressure chamber formed by the rotor () and the stator (), the pressure chamber supply groove () having an outlet () in the pressure chamber delimiting side () of the vane ().

Multipart rotor for a hydraulic camshaft adjuster with a supply of oil to the pressure chambers through the vanes

A multi-part rotor () for a hydraulic camshaft adjuster, including two partial rotor members () which rest against each other along a separation plane () extending perpendicular to the axial direction and which jointly define hydraulic medium ducts () extending within said separation plane () and, including an additional rotor member () that conducts hydraulic medium from opposite axial directions in a targeted manner to different hydraulic medium ducts (). The additional rotor member () or at least one positively engaging anti-twist element () is secured to one or both partial rotor members () for conjoint rotation therewith.

Anti-twist protection for the inner part of a split rotor for a hydraulic camshaft adjuster

A camshaft phaser (), having a drive element (), an output element (), and a cover element (), the cover element () being joined in latching-type, form-locking engagement with the drive element or output element (), and the cover element () having play-eliminator that eliminates a play in the connection.

A switchable component for a valve train of an mternal combustion engine, comprising a housing, a coupling means, an inner element being biased by at least one lost motion spring, a stop means, and an anti-rotation device configured as a thin-walled ring comprising a slit, a rectangular extension projects inwards from a central position from the inner peripheral surface of the ring which extends parallel to a transversal plane of the component on an outer peripheral surface of the housing, the housing comprises an aperture that is complementary in shape to the extension of the ring and said extension extends through said aperture, a counter surface for the extension extends in the form of a longitudinal flattened portion or a longitudinal groove in the outer peripheral surface of the inner element, and the extension extends with a complementary inner surface directly on or into said counter surface.
