摘要： The present invention provides a valve timing regulating device which controls the opening/closing timing of an exhaust valve of an internal engine combustion engine so that upon starting the engine a rotor member is rotated relative to a housing member for reaching in shorter time duration a region in which a lock mechanism functions. The valve timing regulation device includes a fluid pressure circuit controlling the supply and drainage of operating fluid to and from each of the advance angle fluid chamber and the retard angle fluid chamber. The fluid pressure circuit has a fluid pump driven by the internal combustion engine, a control valve controlling, by adjusting the operating fluid supplied from the fluid pump, the supply and draining of operating fluid to and from each of the advance angle fluid chamber and the retard angle fluid chamber, and a check valve disposed between the control valve and the fluid pump such that the check valve is placed close to the control valve for preventing entrance of the operating fluid into the fluid pump.
