Claims

[Scope of utility model registration request]

In an open type compressor, a driven ring that rotates together with the rotating shaft is in sliding contact with a seat ring through which the rotating shaft is inserted, and has a mechanical seal that prevents fluid from leaking toward the rotating shaft. A permanent magnet is interposed between the case fixed to the rotating shaft and the spring pressing the driven ring against the seat ring to collect worn iron particles and prevent them from reaching the sliding surface of the mechanical seal. Open type compressor.
