In particular, by cutting the moisture in the compressed air to be exhausted, the moisture contained in the compressed air discharged from the exhaust port of exhaust valve 7F + '7R is removed from the bleed air [exhaust 1 against the tillage flow of 1]. This is to prevent valves and other parts from rusting due to excess water being sucked in.
