Abstract (en)
[origin: EP0467011A1] A liquid ring gas pump which consists of a pump section (1) and a drive section (6) has operating, cooling and lubricating fluid fed to it from a point (12) in a chamber (11) remote from the shaft, which chamber is partially defined by rotating parts (4, 8). The creation of a rotating liquid ring which might impede the fluid feed is counteracted by a flow disturbance device (15) arranged in the chamber, which device may be designed as a fin or housing projection running longitudinally or radially. <IMAGE>
