A variable cam timing phaser for an internal combustion engine with at
least one camshaft includes a housing (144), a rotor (138), and a phaser
control valve (168). The phase control valve is offset from a center axis
of rotation through the camshaft of the phaser and may also be parallel
to the center axis of rotation. The phaser control valve directs fluid
flow to shift the relative angular position of the rotor relative to the
housing. The phaser may be cam torque actuated, oil pressure actuated, or
torsion assist.
