Abstract:
In a valve timing control apparatus, a supply oil passage, which supplies hydraulic oil to advancing chambers, is formed separately from a discharge oil passage, which discharges the hydraulic oil from the advancing chambers. A spool is configured to reciprocate in a sleeve to enable and disable communication between each corresponding two of an intake oil passage, the supply oil passage, the discharge passage, and a supply and discharge passage. An isolating member is fixed to one end portion of the spool and isolates an air chamber, which is formed between the one end portion of the spool and a bottom portion of the sleeve, from each of the oil passages.
