Diagonal-axial fan-compressor has blades passing from diagonal region into axial region so that flow channel has cover

摘要

The fan-compressor has a closed flow channel and diagonal blades. The blades (2) pass from the diagonal region into the axial region to create the diagonal-axial fan-compressor. The flow channel (4) thus has a cover (3), and the bottom (6) of the flow (5) is either axial or diverges inwards or outwards to divert the flow more efficiently.
