An oil control valve includes an operation unit at an upper part of a cam
cap and an inner part of a head cover that changes a path of fluid into a
continuously variable valve timing unit, and a connector that supplies
power to the operation unit. The operation unit may include a sleeve, a
valve movably located at the sleeve that directly changes the path of the
fluid, and a driving portion that drives the valve. The connector may be
located at the driving portion and exposed to outside the head cover. The
driving portion may be higher than the sleeve, and may be inclined by
approximately 30.degree. with respect to a horizontal line. A hydraulic
line may further be provided in the cam cap to guide the fluid into
chambers of the continuously variable valve timing unit.
