Definitions

  • the differential pressures prevailing to form the purge flow can also be influenced in an advantageous manner in that the supply channel and / or the return channel each have a throttle. This makes it advantageous to generate small volume flows which are particularly suitable for purging small rinsing chambers. This allows the losses caused by the flushing flow to be reduced to a minimum.
  • Fig. 1 and 2 a first embodiment of the gear pump according to the invention is shown.
  • the Fig. 1 shows schematically a cross-sectional view of the gear pump and in Fig. 2 is a sectional view of the gear pump in a sectional plane 90 ° offset from the cross-sectional view shown.
