Definitions

  • Pressure accumulators are known, cf. DE 10 2004 004 341 A1 , Such accumulators are primarily used for damping pressure fluctuations in hydraulic systems in order to protect measuring and control devices, filters and other components integrated in the system from harmful pulsations.
  • a preferred field of use is the use as a pulsation damper in the injection system of internal combustion engines, especially large diesel engines on ships or in combined heat and power plants.
  • pressure fluctuations occur in both the fuel supply system and in the fuel return system, the frequency and severity of the pulsations being determined by the sequence of injection processes, the removal of fuel from the system, the compression, the injection by means of high-pressure injection pumps and the reopening connect to the system.
  • the invention has for its object to provide a pressure accumulator, which is characterized despite a compact design by a particularly good damping effect.
  • the choice of the depth of the "pot” allows an adjustment of the volume ratio of gas space to fluid space according to the respective working conditions.
  • the length of the metal bellows can be chosen to be sufficiently long, even in the case of a desirably small volume of the gas space, so that it has a multiplicity of folds. This ensures that the bellows is in the range of tolerable material stresses in the execution of alternating movements, so that he can perform the largest possible stroke with the largest possible number of repetitions, without the operational safety would be compromised.
  • the stopper may also be constituted by a structure whose structural elements are selected with a view to minimizing the restriction of the flow path caused by them.
  • a further retaining ring fixed on the inner wall of the tubular body and at least one further fastening rod spanning the interior of the retaining ring can be provided.
  • the two storage lids 11 have only one opening, namely inflow opening 15 and outflow opening 17, a large opening cross-section can be provided, so that large flow rates can be achieved.
  • the inner diameter of the tubular body 1 and the outer diameter of the metal bellows 21 are selected such that a sufficiently large annular space 51 is available as part of the flow path belonging to the fluid space 33.
  • the components of the support structure for the cover 27 are chosen so that no significant impediment to the flow path is given, d. H.
  • Both the retaining ring 35 and the mounting rod 39 are, as can be seen from the figures, slim, so that the outer edge of the lid 27 can be flowed around relatively unhindered.
  • the storage housing is formed by a simple tubular body 1 and the housing closure by means of the same trained storage lid 11, results in a particularly simple and inexpensive production.
  • the damper unit 19 can be prefabricated as a unit that can be used as a whole in the tubular body 1 and fixed by means of snap rings 37, 47, there is also a particularly simple installation.
  • the prefabricated as a unit damper unit exists in particular from the actual metal bellows 21, as well as the piston member 31 and the retaining ring 35th
