Abstract
A hydraulically-actuated camshaft phaser includes a camshaft sprocket having a plurality of teeth configured to engage an endless loop that transmits angular motion from the crankshaft to the hydraulically-actuated camshaft phaser; a rotor, coupled with the camshaft sprocket to prevent angular movement between the camshaft sprocket and the rotor, that includes one or more vanes extending radially outwardly forming a plurality of fluid chambers; and a housing that selectively changes angular position relative to the rotor and the crankshaft and is configured to be linked with a variable phase camshaft to change the angular position of the variable phase camshaft relative to the crankshaft.
Claims15
A hydraulically-actuated camshaft phaser, comprising:
- a camshaft sprocket having a plurality of teeth configured to engage an endless loop that transmits angular motion from a crankshaft to the hydraulically-actuated camshaft phaser;
- a rotor coupled with the camshaft sprocket so as to prevent angular movement between the camshaft sprocket and the rotor, the rotor including one or more vanes extending radially outwardly forming a plurality of fluid chambers;
- a housing that selectively changes angular position relative to the rotor and is configured to be directly linked with a variable phase camshaft so as to change an angular position of the variable phase camshaft relative to the crankshaft;
- and
- a camshaft sleeve that is configured to couple with a camshaft sprocket and configured to be slidably received by a camshaft.
