摘要： A valve timing adjusting apparatus has a housing and a vane rotor to form multiple fluid chambers, and a relative position of the vane rotor to the housing is adjusted by the fluid pressure supplied into the fluid chambers. A check valve is provided in a branched passage portion, so that working fluid may not be pushed out from an advancing fluid chamber to a low pressure side, even when the working fluid in the advancing fluid chamber is temporally compressed to increase its fluid pressure due to a torque change applied from a cam shaft to the vane rotor.

摘要： A first one-way valve is provided in a first advance passage connecting a hydraulic pump to a control advance chamber. A second one-way valve is provided in a first retard passage connecting the hydraulic pump to a control retard chamber. A first control valve is provided in a second advance passage to bypass the first one-way valve for communication of the first advance passage. A second control valve is provided in a second retard passage to bypass the second one-way valve for communication of the first retard passage. The first control valve operates by the pilot pressure to close the second advance passage at advance controlling and opening it at retard controlling. The second control valve operates by the pilot pressure to close the second retard passage at retard controlling and open it at advance controlling.

摘要： A shoe housing receives a driving force from a crankshaft and a vane rotor rotates with a camshaft in combination. The vane rotor is received in the shoe housing in such a way as to freely turn. Each of the vanes of the vane rotor partitions each of three receiving chambers into a retard hydraulic chamber and an advance hydraulic chamber. A check valve is disposed in an advance supply passage. The check valve allows a working oil to flow from an oil pump through the advance supply passage to the advance hydraulic chamber and prohibits the working oil from flowing back from the advance hydraulic chamber through the advance supply passage to a drain.

摘要： A first-side check valve prevents a hydraulic fluid from being discharged out of a retard chamber, and a second-side check valve prevents the hydraulic fluid from being discharged out of an advance chamber. A first-side control valve opens or closes a first-side discharge passage by a pilot pressure received through a retard pilot passage. A second-side control valve opens or closes a second-side discharge passage by the pilot pressure received through an advance pilot passage. Another check valve is disposed in a supply passage between a phase switch valve and a branch point, at which a supply passage is branched.

摘要： One of retard passages, which supplies working fluid to one of retard chambers, is a dedicated passage. The other remaining retard passages, which supply the working fluid to the other remaining retard chambers, are branch passages, which are branched from a retard passage that serves as a supply passage. With this construction, a flow quantity of working fluid per unit time supplied from the one of retard passages to the one of retard chambers becomes larger than a flow quantity of working fluid per unit time supplied from the other remaining retard passages to the other remaining retard chambers. Thus, the one of retard chambers can be filled with the working fluid earlier than the other remaining retard chambers.

摘要： A phase control valve, which supplies a drive hydraulic pressure to an advance chamber or a retard chamber, is integrated with a drain switch valve, which controls opening and closing of an advance drain control valve and opening and closing of a retard drain control valve, to form a solenoid spool valve. The advance drain control valve is provided in an advance check valve bypass passage, which bypasses an advance check valve, and is driven by a pilot hydraulic pressure to open and close the advance check valve bypass passage. The retard drain control valve is provided in a retard check valve bypass passage, which bypasses a retard check valve, and is driven by a pilot hydraulic pressure to open and close the retard check valve bypass passage.
