摘要： A variable valve timing device includes a control valve for switching fluid communication among ports. The control valve includes a sleeve, a spool, a movable member, and resilient members. A first resilient member pushes the spool in both of the regions. A second resilient member acts on the spool via the movable member engaged with the spool in an advancing region. In a lock region, the movable member rests on the sleeve to enable the spool to move freely from the second resilient member. As a result, force acting on the spool can be restricted in the lock region. The movable member is supported from a radial inside by the spool and is radially distanced from the sleeve. As a result, it is possible to reduce a sliding resistance acting on the movable member.

摘要： A valve timing adjuster for an internal combustion engine adjusts valve timing. The valve timing adjuster includes a housing, a vane rotor, a regulation device, a fluid route, and an opening/closing control device. The regulation device regulates a rotational phase of the vane rotor relative to the housing to a regulation position located between a full advance position and a full retard position. The fluid route is communicated with a specific chamber that is at least one of an advance chamber and a retard chamber. The fluid route extends via a radially inner part to be communicated with atmosphere. The radially inner part is located radially between the specific chamber and a rotation center. The opening/closing control device opens and closes the fluid route.

摘要： A valve timing adjusting apparatus includes a housing, a vane rotor, and a spiral spring. The spiral spring has a most radially inward part engaged with a rotational shaft of the vane rotor in a state, where the most radially inward part is wound around the rotational shaft. The rotational phase has an intermediate position defined between a full retard position and a full advance position of the rotational phase. The spiral spring has a radially outward segment that is located radially outward of the most radially inward part. When the rotational phase is in a range on a retard side of the intermediate position or on an advance side of the intermediate position, the radially outward segment is engaged with the stopper such that the spiral spring urges the vane rotor in the advance direction or in the retard direction relative to the housing, respectively.

摘要： A primary resilient member urges a primary limiting member into a recess in an inserting direction in a state where a rotational phase is a limited phase in a limited phase range. A relative slide gap is radially provided between the primary limiting member and a secondary limiting member at a location adjacent to a working chamber. First and second primary slide gaps are radially provided between the primary limiting member and radially opposed wall surface sections of the receiving hole. A secondary slide gap is radially provided between the secondary limiting member and a radially opposed wall surface section of the receiving hole. The relative slide gap is larger than the first and second primary slide gaps and the secondary slide gap.
