Abstract
A control valve have a main channel, a channel cross section adjustment spool, a downstream side branching channel, a communication channel, a channel open and close spool, a channel open and close valve, and a upstream side branching channel. In a low rotation speed region of an engine, the channel open and close valve blocks the communication channel. In a medium rotation speed region, the channel open and close spool allows the communication between the downstream side branching channel and the communication channel, and the channel open and close valve allows the communication channel to communicate to slide and move the channel cross section adjustment spool in a direction. In a high rotation speed region, the channel open and close spool blocks the communication between the downstream side branching channel.
