Sealing arrangement for sealing a housing part relative to a moving part with two sealing rings and a protective ring useful in compressor technology ensures uniform sealing ring wear combined with good sealing action

摘要

Sealing arrangement for sealing a housing part relative to a moving part with a radially divided top ring, with its rear side against, in the axial direction a tangentially sealing ring, where rings and are pressed radially against moving part. A graduation is provided on ring which has a protective ring in the peripheral direction. A hollow space is provided between the graduation of ring and ring, which is connected to the low pressure end (po, sic) via a connecting channel.
