Abstract: A pulley for phaser including a toothed outer circumference for accepting a drive force; an inner circumference with at least a first set of lands extending towards a center of the pulley and spaced apart along the inner circumference of the pulley; and an axial retaining feature on the first set of lands for interaction with a corresponding retaining feature of a housing press fit within the inner circumference with the pulley, axially retaining the housing within the pulley.

Abstract: A variable cam timing phaser of a variable cam timing system includes a housing and a rotor moveable with respect to the housing. The rotor and the housing define advance and retard chambers. The variable cam timing phaser also includes a control valve assembly. The control valve assembly includes a valve housing defining a valve housing interior, a supply port, first and second working ports, and an exhaust port. The control valve assembly also includes a piston moveable for controlling flow of the hydraulic fluid through the valve housing interior. The exhaust port is fluidly connectable with a sump through a vent path that is defined by at least one of the valve housing and the rotor. The vent path is configured to prevent air from being sucked into the variable cam timing phaser through the vent path.
