Definitions

  • the object of the invention is to alleviate or eliminate at least individual disadvantages of the prior art.

  • the central axes of the replacement seals are arranged essentially aligned along a longitudinal axis of the magazine.
  • the location and direction information refers to the intended use condition of the compressor.
  • the replacement seals (with the unused sealing elements) are thus arranged in a storage position with aligned, i.e. aligned in a line, central axes along the longitudinal axis of the magazine.
  • This design makes it possible to accommodate a significantly larger number of replacement seals in the magazine ("new magazine") in a space-saving manner. This means that the intervals for service calls can be further increased.
  • the seal has a particularly annular seal carrier, to which at least one annular sealing element is attached.
  • the annular sealing element lies sealingly against the jacket of the compressor piston.
  • the seal can have an axial sealing element for sealing in the longitudinal direction of the compressor piston.
  • the replacement seals are preferably constructed identically to the seal.
  • a plunger piston is preferably provided as the compressor piston, which can be moved back and forth along a cylinder.
  • the compressor piston can be driven in various ways, for example with a hydraulic pump.
  • the compressor can have one or more compressor stages.
  • the magazine has a longitudinal guide for guiding the replacement seals essentially in the direction of the longitudinal axis of the magazine.
  • the longitudinal guide is preferably designed to keep the replacement seals laterally, i.e. in any direction perpendicular to the longitudinal axis of the magazine, essentially free of play.
  • the replacement seals are arranged to be movable only in the direction of the longitudinal axis of the magazine.
  • the longitudinal guide can, for example, have guide rods which extend in the direction of the longitudinal axis of the magazine.
  • the replacement seals are each stacked one above the other along the magazine in a substantially horizontal position (i.e. with the main plane of the replacement seal essentially horizontally aligned).
  • the replacement seals are arranged as a substantially vertical stack along the magazine.
  • the longitudinal axis of the magazine extends essentially in the vertical direction.
  • a large number of replacement seals can be stored in a space-saving manner. The top replacement seal can be moved from the storage position within the magazine upwards into a changing position to enable the replacement seal to be replaced.
