    • PROBLEM TO BE SOLVED: To provide a valve-timing adjusting device which has excellent responsivity of phase control to the advanced angle side regardless of the magnitude of fluctuations in torque, and has a small number of parts. SOLUTION: A shoe housing 12 receives driving force from a crankshaft, and a vane rotor 15 rotates integrally with a camshaft. Then the vane rotor 15 is housed in the shoe housing 12 with flexible rotation, and the vanes 15a, 15b, and 15c of the vane rotor 15 divide each of the three housing chambers 50 into a retard angle oil pressure chamber and an advanced angle oil pressure chamber. Then a check valve 80 is provided at an advanced angle supply passage 223 which is on the side closer to the advanced angle oil pressure chamber 56 than a bearing 2 of the camshaft. Then the check valve 80 allows the flow of hydraulic fluid from an oil pump 202 into the advanced angle oil pressure chamber 56 through the advanced angle supply passage 223, and prohibits backflow of the hydraulic fluid from the advanced angle oil pressure chamber 56 to the oil pump 202 side through the advanced angle supply passage 223.

    • PROBLEM TO BE SOLVED: To provide a valve timing adjusting device in which the structure of a passage for a working fluid into a control valve is simplified.
      SOLUTION: The spool 101 of the control valve 100 opens and closes an advance-angle passage 86 by a force applied thereto from the hydraulic oil supplied from an advance-angle pilot oil passage 103 and the pressing force of an elastic member 100 kept in balance with each other. Therefore, since the oil passage for introducing a hydraulic pressure driving the spool 101 is only an advance-angle pilot oil passage 103, the oil passage structure of the control valve 100 can be simplified, and the structure of the device can be simplified. The elastic member 110 is fitted to the end of the spool 101 in the axial direction of a vane rotor 21. Consequently, even if a centrifugal force is produced according to the rotation of the vane rotor 21, it does not act on the spool 101 and the elastic member 110.

    • PROBLEM TO BE SOLVED: To provide a VVT capable of improving mountability, and capable of reducing the number of part items, by enhancing interlocking accuracy of an OCV and an OSV. SOLUTION: The OCV 22 supplying driving oil pressure to an ignition timing advance chamber A or an ignition timing delay chamber B, and the OSV 29 controlling opening-closing of an ignition timing advance drain control valve 25 and an ignition timing delay drain control valve 28, are arranged as one solenoid spool valve 51. Thus, reliability of the VVT can be enhanced by surely and highly accurately interlocking the OCV 22 with the OSV 29. Due to being one solenoid spool valve 51, processing manhours for installing the OCV 22 and the OSV29 can be reduced, and a mounting space of the OCV 22 and the OSV 29 can be reduced. The number of part items can be further reduced by respectively separately arranging the OCV 22 and the OSV29, and cost can be restrained. COPYRIGHT: (C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a valve timing adjusting device for increasing a working fluid flow rate supplied to an ignition timing delay chamber or an ignition timing advance chamber arranged in a partial fluid passage and connected with a phase check valve, more than a working fluid flow rate supplied to an ignition timing delay chamber or an ignition timing advance chamber connected to the other fluid passage, in at least one phase side fluid passage provided with the phase check valve among an ignition timing delay passage and an ignition timing advance passage. SOLUTION: The ignition timing delay passage 212 supplying a hydraulic fluid to the ignition timing delay chamber 51 is an exclusive passage for connecting an ignition timing delay passage 210 to the ignition timing delay chamber 51. The ignition timing delay passages 213 and 214 supplying the hydraulic fluid to ignition timing delay chambers 52 and 53 are a branch passage branching off from an ignition timing delay passage 211 being a supply passage. With this constitution, since the working fluid flow rate per unit time supplied to the ignition timing delay chamber 51 from the ignition timing delay passage 212 is increased more than a working fluid flow rate per short time respectively supplied to the ignition timing delay chambers 52 and 53 from the ignition timing delay passages 213 and 2314, the ignition timing delay chamber 51 is filled with the hydraulic fluid earlier than the ignition timing delay chambers 52 and 53.

    • PROBLEM TO BE SOLVED: To provide a valve timing adjusting device in which the vibration of a control valve is reduced by reducing the pressure pulsation of the working fluid introduced into the control valve.
      SOLUTION: A retard-angle pilot oil passage 102 and an advance-angle pilot oil passage 103 communicate with near a bearing 6 at its end on the opposite side of the control valve 100. Therefore, the inlets of the retard-angle pilot oil passage 102 and the advance-angle pilot oil passage 103 for introducing the hydraulic oil into the control valve 100 are away from retard-angle hydraulic pressure chambers 41, 42, 43, 44 and advance-angle hydraulic pressure chambers 51, 52, 53, 54. The hydraulic pressure pulsation of the hydraulic oil is reduced away from the retard-angle hydraulic oil chambers 41, 42, 43, 44 and the advance-angle hydraulic oil pressure chambers 51, 52, 53, 54. Consequently, the pressure pulsation of the introduced hydraulic oil can be reduced by introducing the hydraulic oil from the bearing 6 into the control valve 100 via the retard-angle pilot oil passage 102 and the advance-angle pilot oil passage 103.

    • PROBLEM TO BE SOLVED: To provide a valve timing adjusting device having high responsiveness of phase control to a timing advance side irrespective of torque fluctuation and preventing increase in the number of components and complication of a structure.
      SOLUTION: When "positive torque" received by a cam shaft 20 to a timing delay side due to torque fluctuation exceeds a threshold value T, supply of working fluid to each of timing delay oil pressure chambers or timing advance oil pressure chambers and discharge from each of the timing delay oil pressure chambers or the timing advance oil pressure chambers are blocked. Due to this, when the "positive torque" is large, a vane rotor 30 is never pressed back to the timing delay side due to torque fluctuation, and rotational speed of the vane rotor 30 at the time of phase control to the timing advance side is improved. Therefore, responsiveness of the phase control can be improved. Connection/disconnection between a first timing delay passage 22 and a second timing delay passage and a first timing advance passage 23 and a second timing advance passage is performed by rotation of the cam shaft 20. As a result, increase in the number of components is prevented and the structure can be simplified.
