Definitions

  • the channel of cushioning member 8 forms a section of a first channel 7a, which guides the fluid to the atmosphere via a throttled channel junction, in which the first channel 7a and a second channel 7b - a so called bypass channel - disembogues.
  • the second channel 7b fluidically connects the internal space 3 and the first channel 7a in said channel junction.
  • a fluid flow regulating member 9 here screw-like attached to the end cap body 2
  • the outlet guides the fluid to the atmosphere.
  • the cushioning member 8 is formed as a screw with a thread.
