CONTROL VALVE

Document Type and Number:

WIPO Patent Application WO/2015/098858

Kind Code:

A1

Abstract:

In order to reliably transition to a locked state in cases of stopping an internal combustion engine, and to reliably transition to the locked state in cases where a locking mechanism is not in the locked state at the time of starting the internal combustion engine, a spool (50) of a control valve is configured such that the spool can be operated to: a phase control position (PA2, PL, PB2) where the supply/discharge of a fluid to/from an advance port (40A) and a retard port (40B) is controlled in a state where the fluid is supplied to a lock release port (40L); and a lock transitioning position (PA1, PA2) where the supply/discharge of the fluid to/from the advance port (40A) and the retard port (40B) is controlled in a state where the fluid is discharged from the lock release port (40L). A communication path (W) that discharges a portion of the fluid from a pump port (40P) to a drain port (40DA, 40DB) is formed when the spool (50) is operated to the lock transitioning position (PA1, PA2).
