摘要： A valve timing control apparatus is provided having a locking mechanism that can minimize the accumulation of foreign material in a concave engagement part, can minimize the penetration of foreign material to the sliding parts of a locking member, and can reduce the sliding resistance of the locking member. A locking mechanism (5) is provided with a sliding groove (52) provided to an outer rotor (2); a locking member (53) capable of sliding along the sliding groove (52); and a concave engagement part (51) that is provided to the inner rotor (3), is formed to be capable of engaging with the locking member (53) in a state in which the phase of relative rotation is a lock phase, and has an inlet port (58) capable of introducing hydraulic fluid. Flow channels (57) for hydraulic fluid are provided to at least one of the sliding groove (52) and the locking member (53), are formed along the sliding direction of the locking member (53), and are communicatingly connected to the concave engagement part (51).

摘要： A valve opening-closing timing control device includes a solenoid valve having a solenoid mechanism provided with a spool having an oil path groove formed in an outer face thereof, and a sleeve for housing the spool to reciprocate and slide. A wall surface of the sleeve has a first port communicating with a first hydraulic oil supply section, a second port communicating with a second hydraulic oil supply section, and a third port communicating with the side of a hydraulic oil supply source. The spool is driven and set to a first position for supplying hydraulic oil from the hydraulic oil supply source to the first port, a second position for supplying the hydraulic oil from the hydraulic oil supply source to the second port, and a third position outside an area between the first and second positions to prevent supply of hydraulic oil from the first and second ports.
