A straightening apparatus is constituted by a diffuser connected to an inflow pipe having a rectangular section to form an enlarged channel, and eight straightening vanes arranged inside the diffuser. The diffuser has a rectangular sectional surface, and is formed to increase its sectional area from a channel inlet to an outlet. Each straightening vane is arranged to set its surface along the flow direction. Instead of completely partitioning the channel by one straightening vane, the straightening vanes are respectively arranged on the upstream and downstream sides in the flow direction at intervals to form an opening portion at the middle portion of the channel without any partition.

[ What is claimed is:] [1.] A straightening apparatus comprising:an inflow pipe having a fluid flowing therethrough;a diffuser having an inlet and outlet, said diffuser being in fluid communication with said inflow pipe and receiving the fluid from said inflow pipe through said inlet;a first set of straightening vanes disposed adjacent to said inlet of said diffuser;a second set of straightening vanes disposed adjacent to said outlet of said diffuser, each vane of said first set is substantially aligned with a corresponding vane of said second set; andan opening portion disposed between said first set and said second set of straightening vanes, said opening portion permitting fluid flow between corresponding pairs of straightening vanes in said first set relative to pairs of straightening vanes in said second set, and fluid flow between pairs of straightening vanes in said first set and pairs of straightening vanes in said second set which are off set relative to said first set, whereby said straightening vanes substantially reduce energy loss, turbulence, and noise of the fluid while providing substantially uniform velocity of the fluid at said outlet of said diffuser.
