Abstract
A camshaft phaser includes a reservoir cover on a rear side, facing the cams, and a timing wheel on a front side. Fluid is routed from the oil control valve to the reservoir via radial channels defined between a rear cover and a thrust interface. Fluid may also be routed from a radial bearing to the reservoir via these channels. A spool in the oil control valve assembly has an internal passageway to route fluid from a front cavity to the radial channels.
