Definitions

  • a single-stage radial compressor which is characterized in that a single passage or at least one passage distributed over the circumference is arranged in the unbladed diffuser channel, the diffuser channel having at least one annular pressure compensation chamber arranged behind the diffuser wall connect.
  • Such a design is intended to eliminate pressure pulsations which occur when the delivery capacity is reduced.
