20090250028VALVE TIMING ADJUSTING APPARATUS - A valve timing adjusting apparatus includes a housing, a vane rotor, a lock member, a resilient member, and a control unit. The housing includes a limitation groove, limitation stoppers, and a lock hole. When the lock member is received in the groove, the rotational phase is controlled within a predetermined range. When the lock member is fitted with the lock hole, the rotational phase is locked to a lock phase. The resilient member urges the lock member toward the limitation groove and the lock hole in the predetermined direction. The control unit controls a driving force that actuates the lock member in a direction opposite from the predetermined direction. The lock member has small and large diameter portions that are receivable in the lock hole.10-08-2009

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.08-12-2010
20110088645VALVE TIMING ADJUSTER - 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.04-21-2011
20110162601VALVE TIMING CONTROL APPARATUS - A valve timing control apparatus has a regulation member to fix a phase. The regulation member has a main regulation member and a sub regulation member. The main regulation member is inserted into a recess part to regulate the phase. The sub regulation member has an engagement part engageable with the main regulation member in an escape direction Y and disengageable from the main regulation member in an insertion direction X. Further, the sub regulation member has a pressure reception part that receives pressure in the escape direction Y from hydraulic fluid in an operation chamber. The main regulation member is urged in the insertion direction X by a main resilient member. Further, the sub regulation member is urged in the insertion direction X by a sub resilient member. The main regulation member moves in the escape direction Y only by hydraulic fluid, and moves in the insertion direction X only by the resilient member.07-07-2011
20110259289VALVE TIMING CONTROL APPARATUS - 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.10-27-2011
