Control valve assembly of a variable cam timing phaser

A variable cam timing phaser of a variable cam timing system, with the variable cam timing system including a camshaft, said variable cam timing phaser comprising:

• a housing defining a housing interior;
• a rotor disposed in said housing interior and moveable with respect to said housing, wherein said rotor extends along an axis between a first rotor end and a second rotor end and defines a rotor interior, and wherein said rotor is configured to rotate about said axis during operation of the variable cam timing phaser;
• a control valve disposed in said rotor interior and moveable along said axis between a first control valve position adjacent said first rotor end and a second control valve position spaced axially from said first control valve position toward said second rotor end;
• and
• a weight movably coupled to said rotor;
• wherein said weight is configured to actuate said control valve between said first and second control valve positions during rotation of said rotor about said axis.
