Реферат: The fluid machine has at least two interconnected units driven at constant or variable speed. Two individual units (1,2) which are each driven by an individual drive (3,4) are interconnected by a flow guide (9), whereby shut-off and/or reversing valves are individually provided, and at least one drive has a RPM controller (5). The individual units may be the same or different in their style of construction or working principles. Each drive is connected to its respective unit by a rigid shaft connection (6).
