The invention relates to rotary papers or Rotation coopreesors for fluid flow rate or Gaefoerderung, which are controlled by valves and the "nrere promotion retroeae". Funding can be constant or adjustable and the PoerderMengeü the Poerderetroeme to each other can be το * te meter by meter related to each other.

If the pump effect or the compressor effect generate * working chambers, which at the J & oation their volume periodically tergroeesern and downsize when the machine is feeding, can in piston cellsoauart, Fluegelizellenbauart, Zannradzellebauart, ^ rochoid cells be designed or the like *

This significant part of the route restricted not only the performance and the efficiency of previously known multi-current machines but also their practical ones Applicability in industrial practice.

With the invention, the disadvantages mentioned are almost completely overcome The rotary pump or the rotary compressor are known to have suction valves in front of the respective Arranged working chamber, the sole duroh centrifugal force and ejB are pressure valves behind each one Working chamber (or one suction valve each and one pressure each = » valve to each relevant working chamber), which are also based on centrifugal force. The end

The centrifugal force is a particularly reliable wheel more advantageous, but other Yentulversole methods, such as the Closure by flow or medium forces or can be used to celebrate *

The working chambers of the individual working chamber groups can be the same size, or different sizes «This means that the similarity of the conveying flows can vary» be changed "

A particularly useful embodiment of the invention is the dual-flow version, in which one Working chamber in Poerderstrom 1, another in Foerderstrom 2 and the next again in conveyor stream 1 and so on The individual poerder canals end up, depending on the goal ο centric protruding aohsially from the masohine rotor:
