  • VARIABLE CAMSHAFT TIMING (VCT) PHASER ASSEMBLY AND CONTROL VALVE INSTALLED REMOTELY
    Publication number: 20210355847
    Abstract: A variable camshaft timing (VCT) phaser assembly and control valve are employed for use in an internal combustion engine. The VCT phaser assembly has a housing and a rotor. The control valve is installed at a location that is remote of the housing and rotor, and apart from a center bolt site of the housing and rotor. The control valve has a valve housing and a spool located in the valve housing. The valve housing has different ports for fluid communication with a source, an advance line, and a retard line. One or more recirculation paths can be established at various times between the valve housing and the spool, depending upon the position of the spool in the valve housing.
