The control valve is configured such that the sub-valve remains closed when the main valve is controlled and such that the sub-valve is opened after the main valve is closed. Also, a change in the area of opening of the sub-valve relative to the uplift amount of the sub-valve element from the sub-valve seat is larger than that of the main valve relative to the uplift amount of the main valve element from the main valve seat.
