(54) Oil control valve for variable cam phaser


(57) An oil control valve for a variable cam phaser (14) has a secure steel-to-steel fit between the secondary plate (62) of the bobbin (42) and the frame (52) owing to a shoulder (58) formed in the frame (52) against which the secondary plate (62) abuts, and also owing to an o-ring (64) disposed between the bobbin (42) and frame (52). This prevents oil from leaking into the electrical connector (46) of the valve, which advantageously can be oriented parallel to the axis of the valve.
