摘要： A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The inlet-adjustment mechanism includes a plurality of blades disposed about the air inlet and each pivotable about one end of the blade, the blades extending through a slot in the air inlet wall when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Movement of the inlet-adjustment mechanism from the open position to the closed position is effective to shift the compressor's surge line to lower flow rates.

摘要： A composite cooling fan includes a frame, a fan blade and a lateral valve. The frame has an air hole penetrating the frame and a lateral air outlet locating on one side of the frame and connecting with the air hole. The fan blade is disposed in the air hole and includes an impeller, multiple axial blades surrounding the impeller and multiple centrifugal blades surrounding the axial blades. The lateral valve is disposed on the lateral air outlet and includes a valve stem and a switch baffle linked with the valve stem. The valve stem is used for making the switch baffle at the lateral air outlet open or close.
