  • Side channel compressor
    Patent number: 6779968
    Abstract: A side channel compressor comprises an inlet port (42) for gas and an outlet port (44) for compressed gas as well as a side channel (32) which provides a flow connection between the inlet port (42) and the outlet port (44), the cross-section of the side channel (32) diminishing between the inlet port (42) and the outlet port (44). The side channel (32) has at least one section in which it has a cross-section in the form of a half ellipse and in which the maximum depth of the channel (32) continuously diminishes towards the outlet port (44).

  • Multi-stage side channel pump
    Patent number: 6394748
    Abstract: In a multi-stage side channel pump, the efficiency can be optimized in that the geometry of each subsequent stage (14) is adapted to the specific volume of the medium at the outlet of the preceding stage (12) by determining the dimensions of the impeller diameter (D) and of the flow channel diameter (d). The stage pressure is the same for both stages (12, 14). The impeller geometry of the next stage (14) is determined by means of the volume ratio of the preceding stage (12) to the next stage (14), assuming geometric similarity.
