PROBLEM TO BE SOLVED: To provide a control valve capable of surely implementing transition to a lock state of a lock mechanism of a valve opening/closing timing control device, though a constitution having a single spool is applied.SOLUTION: A discharge flow channel R for discharging a fluid from a lock release port 40L, and limiting flow of a fluid flowing to a drain pot 40DA from an advance port 40A or a retard port 40B from which the fluid is discharged, in a case when a spool 50 is operated to a lock transition position P1, is formed on at least a part of an outer periphery of a discharge control land portion 50Le and an inner periphery of a sleeve 40.SELECTED DRAWING: Figure 6 |
