- This filler neck 13 can be closed by means of a screw cap in which an overpressure / vacuum valve is integrated (see function a)).
- a vertical partition 14 is u.a. designed for splash protection and flow calming.
- This partition wall 14 has, according to the two-part AGB housing 11, 11 a, 11 b, an upper partition wall part 14 a and a lower partition wall part 14 b, which are integrally connected to the corresponding housing parts 11 a, 11 b, on.
- This partition 14 divides the compensation chamber 30 into a left zone 19, an entry zone 19, and into a right zone 20, a calmed zone or calming zone 20.
- the entry zone 19 is arranged and formed such that there directly through the inlet opening 25th in the expansion chamber 30 entering coolant flows.
- the calming zone 20 lies opposite the inlet zone 19 and is arranged so that from there the cooled and degassed coolant flows out of the balancing chamber 30 through the outlet opening 27.
- the MIN / MAX display device 15 is arranged in such a way that the coolant level of the coolant is above the coolant inlet opening 25 at a displayed MIN coolant level of coolant located in the compensation chamber 30. This ensures that gas separation is possible even at minimum filling level.
- FIGS. 1 to 4 what is not visible in FIGS. 1 to 4 is arranged in AGB 10 a silicate gel container 16 for admixing or adding corrosion inhibitors (corrosion) into the coolant.
- the AGB 10 For the attachment of the AGB 10 on the cooling module 2, there in particular on the fan frame 9, has, as shown in particular in Fig.2b and 4a to d, the AGB 10 Fixing hooks 17 and mounting clips 18 or Befest Trentsschnapper 18 for appropriate connections with the Fan frame 9 on.
