Abstract

The compressor, in particular lateral channel compressor, comprises a casing member (2, 4) and an impeller (6) which is disposed therein rotatably about an axial axis of rotation and which is spaced from the casing member (2, 4) by a sealing gap (18). The sealing gap is sealed by means of a sealing arrangement which comprises an encircling sealing ring (20) and a spring element (34, 44, 46, 48) that forces the sealing ring (20) against a contact surface (22). The spring load that is applied by the spring element (34, 44, 46, 48) helps obtain automatic, dynamic adaptation to alternating spatial geometries during operation, for example upon temperature fluctuations, which ensures constantly good sealing effects.
