  • Compressor stage
    Patent number: 10519975
    Abstract: Compressor stage with a stator-side intake connection piece via which medium which is to be compressed can be introduced into the compressor stage in the region of the compressor stage, with a stator-side inflow channel via which the medium to be compressed can be conveyed in direction of a rotor-side impeller proceeding from the intake connection piece, wherein the impeller has a radially inner hub, a radially outer cover disk and impeller blades extending between the hub and the cover disk, wherein a plus measuring point and a minus measuring point are provided at the compressor stage for measuring the effective pressure at the compressor stage, and wherein the minus measuring point is positioned upstream of the impeller outside of the stator-side inflow channel in an annular gap which branches off from the inflow channel.

  • Radial compressor and compressor arrangement with such a radial compressor
    Patent number: 9790945
    Abstract: A radial compressor for a compressor arrangement comprising the radial compressor and an axial compressor includes an inlet flow channel bounded by a radially inner hub contour and a radially outer housing contour, in which inlet guide blades are arranged. Via the inlet flow channel a medium to be compressed is supplied to an impeller having moving blades. The inlet flow channel runs diagonally to an axis of rotation of the impeller.
