Patent abstract
A variable camshaft timing (VCT) system for an internal combustion engine is described. In one example, the system includes a spool valve that displaces oil from one phaser chamber to another phaser chamber when the spool valve is moved. The system may respond faster than systems that employ a pump to move oil between phaser chambers.
