    Abstract: Provided is a novel valve timing control apparatus capable of reducing an axial length and of reducing a thickness of a housing. A valve timing control apparatus for an internal combustion engine includes a timing pulley to which a rotational force is transmitted from a crankshaft via a timing belt, a housing configured to be rotated by the timing pulley and including a plurality of shoes provided on an inner peripheral surface thereof, and a vane rotor relatively rotatably contained inside the housing and configured to be rotated in synchronization with a camshaft. The vane rotor includes a vane forming a retard angle oil chamber and an advance angle oil chamber inside the housing in cooperation with the plurality of shoes. A predetermined interval is provided between an outer peripheral portion of the housing and an inner peripheral portion of the timing pulley. An outer peripheral portion of a housing main body of the housing and the inner peripheral portion of the timing pulley are coupled with each other via a plurality of coupling beam portions with intervals in a circumferential direction. The housing main body, the timing pulley, and the plurality of coupling beam portions are integrally formed.

    Abstract: A control device for an internal combustion engine includes a controller. The controller controls the relative rotation phase of the exhaust camshaft in accordance with the relative rotation phase of the intake camshaft. When a request for locking the relative rotation phase of the intake camshaft at an intermediate phase is generated, the controller controls the relative rotation phase of the exhaust camshaft such that the relative rotation phase of the exhaust camshaft is changed to a phase corresponding to the intermediate phase independently from the relative rotation phase of the intake camshaft.

    Abstract: A valve opening/closing timing control device includes a housing main body that includes an opening which opens to at least one side in a direction along a rotational axis and a cover plate closing the opening by making contact with an end surface of the opening, the drive side rotational body rotating synchronously with a crankshaft, and a driven side rotational body housed within the drive-side rotational body and defining an advance chamber and a retardation chamber relative to an inner peripheral surface of the housing main body, the driven-side rotational body rotating integrally with a camshaft and coaxially with the rotational axis. In addition, the housing main body includes a hard layer formed at least at the inner peripheral surface of the housing main body in a surface thereof excluding the end surface of the opening.

    Abstract: A valve timing control device is switchable between a first state in which a fluid is supplied to a communication flow path to lift a restriction by a restriction member and release a lock by a lock member, a second state in which the fluid is supplied to a retarded angle chamber to release the lock by the lock member and set the restriction by the restriction member, and a third state in which the restriction member is restricted and the lock member is locked without supplying the fluid to the communication flow path and supplying the fluid to the retarded angle chamber, and is configured such that the minimum cross-sectional area of an advanced passage for supplying the fluid to an advanced chamber is greater than the minimum cross-sectional area of a retarded passage for supplying the fluid to the retarded angle chamber.
