Abstract
A geared multishaft turbocompressor with impellers arranged in series in terms of flow, are attached to two or more pinion shafts (6), which are arranged in parallel to one another and are driven directly via a central gear (5) or indirectly via pinion shafts at the circumference of the central gear (5). A plurality of impellers (8, 8a) are arranged in series, via the interstage diaphram of a disk-type diffuser (9) and of a return ring (10), on at least one pinion shaft end (6) in high-pressure stages following low-pressure stages (first pinion shaft or first and second pinion shafts) after the second or third pinion shaft (6). Reversing the direction of flow, i.e., admission of the gas on the high-pressure side and discharge of the gas on the low-pressure side, as well as with simultaneous reversal of the direction of rotation, a radial expander (turbine) is obtained with the same basic design.
