Definitions

  • the invention relates to a closure cap for containers, housings, bottles or the like, which can be filled with a liquid or a solid, at least one opening of the container or the like being releasably closable with the closure cap, and wherein a pressure compensation device with at least one in the closure cap Membrane made of a liquid-impermeable or solid-impermeable but gas-permeable material and a surge protection element made of a gas-permeable material for breaking the surge pressure of the liquid or the solid are installed on the membrane.
  • the measuring device housing is only filled to about 90 to 95% with the liquid, for example glycerine silicone oil.
  • the liquid can now expand in the remaining space, but the problem is the impermissible pressure on the housing walls or devices in the housing only relocated because of the volume expansion in the housing existing air is compressed.
  • such a process led to intolerable falsifications of the measured values.
  • Pressure relief valves can only do justice to one aspect, since they prevent the escape of liquid, but there is no gassing in the case of negative pressure, for example after the relevant container or housing has cooled.
  • Double-acting valves are conceivable, but they require such a high cost that one is usually satisfied with less demanding valve solutions.
  • Solutions are also conceivable in which one or more walls of the container or housing are elastically deformable in such a way that they can follow the overpressure or underpressure in the housing, but it is obvious that such solutions are suitable for use severely limit the container or housing or the like and, moreover, can only be used with containers or housings or the like which only have to cope with small pressure differences.
