  • the separation can optionally also comprise at least one bypass opening with which a (predetermined) limited Exchange flow is adjustable or set.
  • the bypass opening(s) is/are significantly smaller than the base area of the chamber or the separation, in particular with a surface area of less than 30% or even less than 15%, so that a permanent separation of the chamber volumes is achieved.
  • the diameter or cross-section of the bypass opening(s) is in particular not smaller than the diameter or cross-section of an inlet connection which is arranged on the upper, first chamber.
  • Each of the chambers has several inlet connections and several outlet connections.

  • the chambers are designed in such a way that that the release of heat into the environment is limited or even (largely) prevented.
