A bypass valve 100 for a recuperator 50 is situated in a duct 70 that surrounds the recuperator, and may be adapted to open or close an opening of the recuperator to allow a fluid to bypass or enter, respectively. The fluid used may be the exhaust gases from a turbine 20, which may exit via a low angle diffuser 25, and the recuperator, which may be of an annular type, can be mounted around the diffuser. The recuperator comprises a heat exchanger 60, which in turn features cold 62 and hot 64 sides. In use, fluid from the turbine enters the hot side, in order to heat compressor delivery air in the cold side. The valve 100 may be a poppet valve with a conical face 114, and furthermore may features a domed rear surface 58. The valve may move parallel to the plane of the duct, to open or close the recuperator opening. |
