RE: Why Recirculation line (valve) is p

A bit more detail would help, but I guess it is so that when the engine starts or engages it doesn't see a sudden very large load.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Why Recirculation line (valve) is p

When starting up against a high, or full discharge head, a bit of time recirculating while the IC engine is running up to operating speed rpm is often needed. Internal combustion engines do not produce high torque at low rpm, quite the opposite of electric drivers, which give max torque at low rpm.

Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."
