I uploade this photo to the English Wikipedia about an hour ago and I am now uploading it to Commons. This photo of a centrifugal compressor was obtained from Figure 34.21 in Handbook for Notification of Exports to Iraq, Annex 3, United Nations Security Council Resolution 1051 (1996), prepared by the U.S. Department of Energy, Nuclear Transfer and Supplier Policy Division. A copy is available online at Chapter 5 of Annex 3. - Mbeychok 08:19, 19 January 2007 (UTC)

Caption from the original PDF:

A single stage centrifugal compressor (left) driven by an electric motor (right) through a gearbox (center). A low-speed coupling connects the motor to the gearbox, and a high-speed coupling connects the gearbox to the compressor. Process gas enters the compressor through the flanged opening at left center and is discharged through the flange in the upper left corner of the photograph. The impeller can be seen just inside the inlet port.
