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.
