Abstract:
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.
