Definitions

  • the present invention relates to a piston compressor, in particular a radial piston compressor, according to the preamble of claim 1 or claim 2.
  • a piston compressor is a component of fluid technology.
  • the piston-working chamber combinations are arranged radially and perpendicular to the drive shaft, unlike an axial piston compressor.
  • the delivery or reciprocating movement of each individual working piston is usually caused by an eccentric located on the drive shaft.
  • Piston compressors, especially radial piston compressors typically comprise several piston-working chamber combinations that extend radially from the drive shaft in a star-shaped configuration.
  • the radial piston compressor pumps a fluid from a low-pressure region to a high-pressure region.
  • Both collection volumes can be routed, for example, in ducts (ring ducts or similar).
  • the discontinuous suction at the inlet duct or inlet valve and the discharge at the outlet duct or outlet valve generate pressure pulsations in the respective collection volume, which can propagate into the refrigerant circuit via the internal ducts and the compressor connections.
  • An excessively high pulsation level can lead to the emission of disturbing noise into the passenger compartment, for example, via the heat exchangers.
  • a refrigerant compressor which has a refrigerant suction chamber and a refrigerant discharge chamber, as well as a refrigerant distribution device, which has a distribution line and bypass lines that connect the distribution line and the suction chambers of the compressor units.
  • a refrigerant discharge device is provided, which has a discharge line and bypass lines that connect the discharge line and the discharge chambers of the compressor units.
  • the refrigerant compressor proposed here is characterized by is characterized in particular in that the compressor further comprises pressure equalization means which are designed to connect the suction chambers of at least two compressor units and/or the discharge chambers of at least two compressor units.
