Side channel compressor having a seal assembly

A seal assembly for a side-channel compressor comprising:

• a sealing device disposed in an annular groove of a compressor housing, the compressor housing including a hub receptacle space, the sealing device configured to seal a gap between the compressor housing and an impeller, the annular groove defining an internal edge relative to a central axis of the compressor, and having an annular web adjacent to the hub receptacle space, the annular web extending into the annular groove and defining a retaining edge, where the sealing device is configured to be forced radially outward with respect to the central axis to seal the gap, and
• a sealing-device-holding device configured to hold the sealing, and which includes a main holding body,
• wherein the sealing-device-holding device has at least one of an oblique projection or a curved projection bent out from the main holding body, the oblique projection or curved projection having a free end abutting against at least one of the internal edge or the retaining edge, and projecting radially with respect to the central axis from the main holding body and supported in relation to the housing, forcing the sealing device radially outward with respect to the central axis and in contact with the impeller.
