Technical Examples

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.
